I found him in a kitchen located in Toronto, Ontario, Canada.


This looks very similar to a click beetle. Some of them are pretty popular in south Canada.


Beetle

The beetle is a small sized invertebrate that is known to be incredibly versatile and is found in numerous different shapes and sizes. Beetles are found in nearly every different habitat on Earth and are only absent from the freezing polar regions.

The beetle has the largest number of sub-species out of all the insects, with 40% of all recognised insects being classed as beetles. There are more than 350,000 different species of noted beetle, however, scientists estimate the real number is between 4 million and 8 million beetle species.

As with other species of insects, the body of the beetle is comprised of three sections all coated in the hard outer shell, which are the head of the beetle, the thorax of the beetle and the abdomen of the beetle. Beetles also have antennae which are used to understand the surroundings of the beetle and are made of about 10 different sections.

Beetles are believed to play a vital role in whichever ecosystem they are inhabiting mainly as they consume the debris from plants and animals including fallen petals and animal dung. All animals that ingest decomposing material are working wonders for the soil as they are consuming a large proportion of the compounds that would otherwise be absorbed into the soil, such as carbon dioxide and nitrogen.

The beetle is an omnivorous animals and feeds on whatever it can find but generally plants and fungi and the debris from both plants and animals. Some bigger species of beetle have been known to eat small birds and even small species of mammal. Other species of beetle feed of the dust from wood and therefore enjoy burrowing themselves into trees.

Due to their small size and wide, diverse range, beetles are prey to numerous species of animal from other insects to reptiles, birds, fish and mammals. The exact predators of the beetle however are largely dependent on the size and species of the beetle and the area in which the beetle inhabits.

Recently, the Asian long-horned beetle has been found in number of North American states with the beetle having quickly gained a name for itself as an agricultural pest. The Asian long-horned beetle is a type of bark boring beetle which means that they dig themselves into wood.


Ladybird Beetle

All the ladybird beetles, with the exception of the members of one vegetation-eating genus, are carnivorous. In both the adult and larval stages they feed on insects harmful to plants, such as aphids and scale insects. Because of the help ladybird beetles render farmers in destroying agricultural pests, the beetles were popularly regarded in the Middle Ages as instruments of benevolent intervention by the Virgin Mary, whence the common name ladybird.

A common North American species of ladybird beetle, the nine-spotted ladybug beetle, is orange above, spotted with black. Adults of the two-spotted ladybug beetle often hibernate in houses during winter. This beetle is orange above, with a single large black spot on each elytron (protective outer wing). The convergent ladybug beetle is a western American species, the adults of which commonly swarm in large numbers on mountain peaks. These swarms are collected by western agricultural firms and are distributed to farmers for aphid control. The vedalia, an Australian species, has been imported into California to fight the cottony-cushion scale insect, which attacks citrus trees.

A few ladybird beetles are injurious to humans. The Mexican bean beetle is the most serious of these agricultural pests, feeding on the leaves and pods of bean plants. This beetle, which has spread throughout the United States, is brownish-yellow above, marked with eight black spots. The squash ladybird feeds on the leaves of plants of the gourd family.

Scientific classification: Ladybird beetles make up the family Coccinellidae. The nine-spotted ladybug beetle is classified as Coccinella novemnotata, the two-spotted ladybug beetle as Adalia bipunctata, the convergent ladybug beetle as Hippodamia convergens, and the vedalia as Rodolia cardinalis. The few ladybird beetles that are agricultural pests belong to the genus Epilachna. The Mexican bean beetle is classified as Epilachna varivestis, the squash ladybird as Epilachna borealis.


These three Australian beetles are hard to find. So two researchers named them after Pokémon.

Yes, professor, Pokémon are real.

Or at least, they can be if you name a new beetle species after the iconic pocket monsters. That's the lesson Darren Pollock, a professor of biology at Eastern New Mexico University found out when a fellow researcher in Australia contacted him with the discovery of several new beetles.

In truth, they don't actually look much like Pokémon. But Pollock and the researcher, Yun Hsiao at The Australian National University, opted to name the newly found insects after the names of three extremely rare Pokémon from the popular series: Articuno, Zapdos and Moltres.

“I always feel it is nice to connect the public popular culture to biotaxonomy to raise the people’s concern on the conservation of the amazing diversity of our earth ecosystem,” Hsiao, a Ph.D. candidate, wrote in an email to USA TODAY. “And I really appreciate the biodiversity of Pokémon world, which is actually based (in) real life diversity.”

Hsiao discovered the beetles while he was scouring the Australian National Insect Collection – which, according to its website, houses more than 12 million specimens – and found there were new species of a genus of beetle that Pollock had previously studied.

Hsiao contacted Pollock and the two described the beetles. They've been dubbed Binburrum articuno, Binburrum zapdos and Binburrum moltres. The two published their findings in the journal The Canadian Entomologist in December.

The three bugs are named after their Pokémon counterparts - namely, birds of ice, lightning and fire. The names have generated some attention, Pollock and Hsiao said.

The scenario is a bit of reality mirroring fiction.

Legendary Pokémon tend to come in sets of three in most games in the series. That pattern crossed Hsiao’s mind when the beetles were discovered, he said.

Pokémon professors in the games ask trainers to help with cataloguing the creatures with a high-tech encyclopedia called a Pokédex. There are already a few beetle-like Pokémon in the popular series: Heracross, with its giant horn, bears a striking resemblance to the Japanese rhinoceros beetle, for example.

Pollock said it was Hsiao’s idea to name the beetles after the rare legendary bird Pokémon. In the original Red and Blue games – the “first generation” games, Hsiao’s favorite – in the U.S., there was only one of each type of bird available to the player. Naming the beetles after the one-of-kind birds was a nod of sorts to how rare the beetles are, Pollock said.

“The number of specimens we looked at in this research project were very few,” Pollock said. “Just a handful of specimens.”

Choosing Pokémon names meant the chances of duplicating an already-used name were slim, Pollock said.

“One of the things that’s very important when you’re describing new species is you absolutely cannot duplicate someone else’s species name,” Pollock said. “There’s a genus, and then a species, like Homo sapiens (humans), or Musca domestica (housefly), or Binburrum articuno. If you’re going to be describing a new species, one of the easiest ways to make sure that you don’t duplicate somebody’s old name is to make it something new and different, or clever."

He added, “Back when the species were being described hundreds of years ago, the Moltres or Zapdos and Articuno… those words weren’t around.”

The beetles have received more attention than Hsiao and Pollock expected.

“It’s spread quite a lot more than I ever thought it would for dinky little beetles from Australia,” Pollock said.

He added, “The bottom line is, it’s documenting the need for describing species on the planet. There’s just so many species that need to be described, and there’s so few people that are able to do it. That’s a win-win, I think.”

Hsiao is the more hardcore Pokémon fan of the pair of researchers, Pollock said. Still, the professor has fond memories of the video game and television series. This year marked the 25th anniversary of the first games' release in Japan.

“I remember getting up with my son and watching Pokémon on TV and standing in line on Black Friday and buying a Pokemon Yellow GameBoy, which he still has,” Pollock said.

Plus, he remembers his son searching for a rare Charizard card when opening Pokémon Trading Card Game booster packs.


What's the name of this beetle? - Biology

Each of these four processes is a basic mechanism of evolutionary change.

Mutation
A mutation could cause parents with genes for bright green coloration to have offspring with a gene for brown coloration. That would make genes for brown coloration more frequent in the population than they were before the mutation.
Migration
Some individuals from a population of brown beetles might have joined a population of green beetles. That would make genes for brown coloration more frequent in the green beetle population than they were before the brown beetles migrated into it.
Genetic drift
Imagine that in one generation, two brown beetles happened to have four offspring survive to reproduce. Several green beetles were killed when someone stepped on them and had no offspring. The next generation would have a few more brown beetles than the previous generation — but just by chance. These chance changes from generation to generation are known as genetic drift.

All of these mechanisms can cause changes in the frequencies of genes in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift cannot operate unless there is genetic variation — that is, unless some individuals are genetically different from others. If the population of beetles were 100% green, selection and drift would not have any effect because their genetic make-up could not change.


Identification, biology and management of Colorado potato beetle

This year, I’ve had a handful of people ask me about managing Colorado potato beetle (CPB) in Iowa. Read more about CPB identification and biology here. These conversations were with producers growing over 5 acres of potatoes and having a difficult time reducing CPB pressure. With the help of Dr. Ian MacRae at the University of Minnesota, I put together an IPM plan for this devastating pest. Colorado potato beetle (CPB) is a major pest of potato that is native to America and Mexico. It's been in Iowa for over 150 years and has a long history of devastating outbreaks. This article provides some basic information on CPB identification life cycle and damage to potato.

Identification

Adult CPBs are oval in shape and 3/8 inch long. They have a yellow-orange prothorax (the area behind the head) and yellowish white wing covers with 10 narrow black stripes. Females lay clusters of bright yellowish-orange oval eggs on the underside of leaves. Eggs turn dark red just before hatching. When larvae first hatch from eggs, they have brick red bodies with black heads. Older larvae are pink to salmon colored with black heads. All larvae have two rows of dark spots on each side of their bodies.

Adult CPBs overwinter in potato fields, field margins and windbreaks. They become active in the spring at about the same time potatoes emerge (sometime in May). Adults feed for a short time in the spring and then begin to mate and lay clusters of 10-30 eggs on the undersides of leaves. Each female can lay up to 350 eggs over 3-5 weeks.

Eggs begin to hatch within two weeks, depending upon temperatures. Larvae remain aggregated­ near the egg mass when young but begin to move throughout the plant as they eat the leaves. Larvae can complete development in as little as 10 days if average temperatures are in the mid 80’s. It will take over a month if temperatures average near 60°F. Larvae mature through four instars before they drop from the plant, burrow into the soil and pupate. There can be two generations in Iowa. Because eggs are laid over time, all life stages of CPB can be present at the same time in a potato field by July.

Both larvae and adults feed on the foliage of potatoes and, if left untreated, can completely defoliate plants. In addition to potato, they may also feed on eggplant, tomato, pepper, and other plants in the nightshade family (Solanaceae). Old larvae (i.e., 4th instars) are responsible for as much as 75% of feeding damage. Potatoes can usually tolerate substantial defoliation, up to 30%, when they are in the vegetative stage, but they are much more sensitive to the effects of defoliation when tubers are beginning to bulk and they can only tolerate about 10% defoliation. Tuber bulking begins soon after flowering, making this time critical for CPB management.

In general, CPB are very difficult to suppress because of their biology. Successful suppression will take an integrated approach with a focus on being proactive. I often recommend using IPM (integrated pest management) to help with field crop pests. It should include some or all of the following tactics:

1. Cultural. Much of what farmers/gardeners do to grow plants favors insect development. If we can mix up our growing conditions to interfere with the food and habitat pests need to survive, that will greatly discourage them from devastating our crops. For example:

  • Sanitation, or removing potential food and habitat, is an effective starvation technique. If potatoes or solanaceous plants (e.g., eggplant, peppers, tomatoes), are not available when CPB adults first emerge in the spring, they will seek out alternate hosts, such as nightshade and ground cherry. Remove old plants and weeds in and around potato plots before, during and after the season to eliminate food sources.
  • For small plantings, hand removal can be effective. Drop CPB adults and larvae in a pail filled with soapy water. Also remove or crush the eggs on the underside of leaves. Adults can fly into plots so be sure to check your potatoes regularly. Hand removal may be less practical in larger plots.
  • Crop rotation, or only growing potatoes only every other year, may help reduce beetle populations if no potatoes are being grown within a radius of ¼-½ mile away and temperatures are not excessively warm. Moving the area that is planted with potato, is largely ineffective because the CPB can fly long distances when temperatures exceed 70°F.
  • Date of planting will probably not be that effective tactic like for other pests. Most potatoes will not germinate until the soil temp is 40°F and the adult tend to emerge 2-4 weeks later. Planting seed pieces too early can actually cause germination issues, like diseases and rotting.
  • Tillage is not effective unless deep tillage is used (and even then they can survive). The adults overwinter in soil and leaf litter and are quite capable of digging into and out of the soil after being buried.
  • Exclusion with cages or row covers is not recommended for CPB because the supplies are expensive and time consuming to maintain.

2. Genetic. Planting an early-maturing variety will allow you to escape much of the damage caused by adults emerging in midsummer. Check seed catalogs for varieties that mature in less than 80 days. Yields on early-maturing varieties are not as large, and often these varieties do not store as well as the popular Russet Burbank potato.

3. Biological. There are few natural enemies of CPB, like predatory stink bugs and beetles. There is also a naturally-occurring fungus, Beauveria bassiana, that will kill larvae and adults. Unfortunately, biological control has minimal impact on CPB populations compared to other crop pests. I wouldn’t recommend planting flowering crops around or within potato plots to attract natural enemies, or releasing predators to suppress CPB.

4. Scouting. To focus your suppression efforts, I highly recommend the use of tracking air temperature. Insects develop based on accumulating heat units, or degree days (DD) just like most plants and other invertebrates. The lower developmental threshold, a point at which no development will occur, for CPB is 52ºF. The very first adult you see in the spring sets the “biofix” where accumulating DD begins:

  • 120 dd post biofix - eggs are maturing, look for the beginning of 1st instars
  • 185 dd post biofix - 1st instars completing, look for the beginning of 2nd instars
  • 240 dd post biofix - 2nd instars completing, look for the first 3rd instars
  • 300 dd post biofix - 3rd instars completing, look for the first 4th instars
  • 400 dd post biofix - 4th instars completing, larvae will start dropping to ground to pupate

*You would want to target your scouting and suppression efforts on the first generation, 120-200 DD post biofix. Every summer is a bit different, so it is important to monitor each season rather than depend on calendar dates.

5. Thresholds. Even when implementing proactive IPM tactics, like cultural tools, there will be seasons when CPB still have outbreaks. In general, I recommend applying insecticides to protect yield based on CPB leaf defoliation: 20%-30% before flowering, 5%-10% at flowering, and 15%-20% post flowering. Estimating defoliation by eye takes practice because people tend to overestimate leaf area removed. There could be some seasons where these thresholds are not met and insecticides are not required.


Scouting for Colorado potato beetle eggs and young larvae, in addition to estimating defoliation, will inform your pest suppression plan and protect the crop!

6. Chemical. Depending on the size of the potato plots and the historical outbreaks on the farm, insecticides may be required to protect the crop. This method can be used with other IPM tactics and in moderation (e.g., a last resort when other tactics are not working). I highly recommend scouting and using thresholds to determine if applications are needed (see previous sections). There is a wide spectrum of chemical control products that target CPB, ranging from organic to restricted-use pesticides. It is important to read the label and follow all the directions, particularly how soon you can harvest potatoes after applications. Keep the following considerations in mind:

  • It is easier to kill young larvae compared to older larvae and adults.
  • Products are more effective when making direct contact with the body. Getting small droplets to contact CPB can be challenging given they feed and aggregate on the undersides of leaves.
  • Targeting suppression efforts of the first generation can greatly reduce the impact of the second generation when plants are more sensitive to defoliation.
  • Most chemicals are broad spectrum, meaning they will kill most insects that make contact with the application (e.g., pollinators, predators, etc.). This is true of organic and synthetic insecticides.

Microbial insecticides (the following products are approved for organic production and considered low risk to humans):


General features

Beetles are found in nearly all climates and latitudes, except in such extreme environments as those in Antarctica and at the highest altitudes. They are found on subantarctic islands, close to the northern extremes in the Arctic, and on many mountaintops. Although many species occur in temperate environments, the number of species is greatest in the tropics in general, individuals of a species are most abundant in temperate areas, and fewer individuals of more species are found in the tropics.

Some species are solitary others occur in aggregations. Predators such as the ground beetles (Carabidae) are more apt to be found alone, as are many long-horned wood-boring beetles ( Cerambycidae) and weevils (Curculionidae). Ladybugs ( Coccinellidae), leaf beetles (Chrysomelidae), pleasing fungus beetles (Erotylidae), darkling beetles (Tenebrionidae), checkered beetles (Cleridae), bess beetles (Passalidae), sap beetles (Nitidulidae), and some species of scarab beetles (Scarabaeoidea) are often found in aggregations of one or several different species.

Most families contain both widely distributed species and some with very limited ranges. Wide distribution in this sense refers to a zoogeographical or faunal region limited distribution, to a single valley, plain, island, altitude zone, or vegetation type on a mountain.


Rhinoceros beetles are herbivorous insects named for the horn-like projections on and around the males' heads. Most are black, gray, or greenish in color, and some are covered in soft hairs. Another name given to some of these insects is the Hercules beetle, because they possess a strength of Herculean proportion. Adults of some species can lift objects 850 times their weight. (That would be equivalent to a human lifting nine fully grown male elephants.) One way the beetles use this extreme strength is to dig themselves into leaf litter and soil to escape danger. Their horns also help them to do this. Rhinoceros beetles can grow up to six inches (15 centimeters), making them some of the largest beetles in the world.

Rhinoceros beetles are found on every continent except Antarctica. In the United States, they live in the south from Arizona northeast to Nebraska and eastward. Leaf litter, plants, and fallen logs provide a safe hideout for rhinoceros beetles during the day.

All rhinoceros beetles are herbivorous. The adults feed on fruit, nectar, and sap. The larvae eat decaying plant matter.

The horns of the male rhinoceros beetle are used to drive other males away from a female beetle during mating rituals. Females lay about 50 eggs, which hatch into larvae. After several molts, they eventually reach adult size and form. Longevity varies among species, but a typical lifespan is one to two years. Much of this may be spent in the larval stage.

The beetles' population status probably varies among species. Rhinoceros beetles are collected as pets, and in some Asian countries, gamblers place bets on which of two male beetles will knock the other off a log.

When disturbed, rhinoceros beetles can produce hissing squeaks. These aren’t actually vocal noises—instead, they’re produced when the beetle rubs its abdomen and wing covers together.

Meet the diabolical ironclad beetle, which can survive being run over by a car

Scientists are unraveling the mystery of a bug with one of the coolest names in the animal kingdom: the diabolical ironclad beetle.

Phloeodes diabolicus has one of the toughest natural exoskeletons scientists have ever seen. According to research published Wednesday in the journal Nature, the insect's armor is so durable, few predators have successfully made a meal out of it &mdash and it can even survive getting run over by a car.

This is a bug that scientists famously need to drill a hole into before they can stick a pin through it.

A team from Purdue University and the University of California, Irvine (UCI) have deduced that when an extreme amount of pressure is put on the beetle, its "crush-resistant" shell adapts to the situation by stretching, rather than shattering. Its nearly indestructible shell, coupled with its convincing acting skills when it comes to playing dead, leave the beetle with few predators.

Native to desert habitats in Southern California, the diabolical ironclad beetle has an exoskeleton that's one of the toughest, most crush-resistant structures known to exist in the animal kingdom. David Kisailus / UCI

"The ironclad is a terrestrial beetle, so it's not lightweight and fast but built more like a little tank," lead author David Kisailus, a UCI professor of materials science and engineering, said in a news release. "That's its adaptation: It can't fly away, so it just stays put and lets its specially designed armor take the abuse until the predator gives up."

In compression tests, researchers found the beetle can withstand a force of about 39,000 times its body weight &mdash the equivalent of a 200-pound man enduring the weight of 7.8 million pounds.

Trending News

So, how does the seemingly indestructible bug manage to survive against all odds?

Scientists have found that the shell of the bug, which is native to desert habitats in the Southwestern U.S., has evolved to protect it. Specifically, its elytra &mdash the blades that open and close on the wings of aerial beetles &mdash have fused together to act as a solid shield for the beetle, which can't fly.

Analysis of the elytra revealed that it's made of layers of chitin, a fibrous material, and a protein matrix. Its exoskeleton contains about 10% more protein by weight than that of a lighter, flying beetle.

Under compression, the jigsaw puzzle-like structure of the elytra doesn't snap as expected, but rather, fractures slowly.

A cross-section of the medial suture, where two halves of the diabolical ironclad beetle's elytra meet, shows the puzzle piece configuration that's among the keys to the insect's incredible durability. Jesus Rivera / UCI

"When you break a puzzle piece, you expect it to separate at the neck, the thinnest part," Kisailus said. "But we don't see that sort of catastrophic split with this species of beetle. Instead, it delaminates, providing for a more graceful failure of the structure."

Scientists believe that understanding just what makes the iron beetle so tough will have practical applications for humans, too. Kisailus said that new, extra-strong materials based on the bug's characteristics will drastically improve the durability of aircraft, automobiles and more.

Kisailus and his team mimicked the structure of the bug's exoskeleton using carbon fiber-reinforced plastics. The result was both stronger and tougher than current aerospace designs.

"This study really bridges the fields of biology, physics, mechanics and materials science toward engineering applications, which you don't typically see in research," Kisailus said. "Luckily, this program, which is sponsored by the Air Force, really enables us to form these multidisciplinary teams that helped connect the dots to lead to this significant discovery."

common names: Nitidulid Beetle, Oak Wilt Beetle, Sap Feeding Beetle

scientific name: Order Coleoptera, family Nitidulidae, several species

size: Adult--1/4"

identification: Adults look like tiny rove beetles.

biology and life cycle: Nitidulids inhabit fungal mats beneath the bark of diseased red oaks (Quercus texana and Quercus shumardii). Infectious beetles emerge from the fungal mats and deposit oak wilt spores in wounds on healthy trees by feeding in sap.

habitat: Texas live oaks, red oaks, and blackjack oaks.

feeding habits: Sap from cuts or wounds on oak and other trees. Also feed on rotting fruit in the orchard.

economic importance: This beetle spreads the devastating oak disease called oak wilt (Ceratocystis fagacearum), which has killed thousands of live oaks and red oaks in Texas.

natural control: Keep trees in healthy condition so they can resist the beetle and disease. Mulch or maintain the natural habitat under trees.

organic control: The Texas Forest Service recommendation is to trench to separate the roots of infected trees from those of healthy trees and inject chemical fungicide into the trees. We do not recommend that approach. There is strong anecdotal evidence that the Sick Tree Treatment works to prevent the disease and save infected trees.

insight: Infestations cause fungal mats to form on red oaks only, not on live oaks. For that reason, live oak wood can be used for firewood without any worry. Red oak wood needs to be stacked in a sunny location and covered with clear plastic to form a greenhouse effect to kill the beetles and fungal mats. When oaks are ground into mulch, the aeration kills the pathogens and eliminates the possibility of disease spread.

Beetles in the family Nitidulidae, sometimes called sap beetles. These beetles have been
implicated as the primary carriers of fungal spores of the oak wilt pathogen to healthy trees.

Trees of highly susceptible red and white oak species wilt rapidly from the top down and are killed completely within four to six weeks. Moderately susceptible species wilt more slowly. Trees of species with low susceptibility may "wall off" the disease and survive with only partial death of branches.

Healthy trees are infected by fungal spores that enter wounds on branches and trunks. Insects such as sap beetles (Nitidulidae) and bark beetles (Scolytidae) are attracted to oozing sap from fresh tree wounds. The beetles become contaminated with fungal spores and are believed to be the primary agents of long-distance spread from diseased to healthy trees. Thus, the importation of all wood with bark is prohibited since it may contain contaminated beetles. The disease also spreads slowly from tree to tree via natural root graphs.

Natural selection
Imagine that green beetles are easier for birds to spot (and hence, eat). Brown beetles are a little more likely to survive to produce offspring. They pass their genes for brown coloration on to their offspring. So in the next generation, brown beetles are more common than in the previous generation.
