Elmidae riffle beetles
found on vegetation in those habitats. Larvae are strictly aquatic, but otherwise share the same habitats as adults. Adult riffle beetles are small (1-8 mm long), dark, elongate, hard-bodied beetles, with relatively long legs and tarsal claws. The antennae are at most slightly clubbed, usually slender (this distinguishes them from species in an otherwise-similar family, the Dryopidae). The ventral surface of the body adult riffle beetles is covered with an extremely dense (millions/mm^2) layer of tiny
Lasioderma serricorne cigarette beetle
beetles rarely leave the food store that they were born in, but if the store is depleted, they can fly to a nearby food store and colonize it. Cigarette beetles use their senses of touch, sight (minimally), and chemical receptors to perceive their environment and communicate with other beetles. The most common form of communication between beetles is through the use of pheromones, which they use to attract mates and deter oviposition near an existing oviposition site. Cigarette beetles are best known for
Cotalpa lanigera goldsmith beetle
Goldsmith beetles, Cotalpa lanigera, are found in the eastern, central, and southwestern United States as well as southeastern Canada. Goldsmith beetles inhabit deciduous forests, woodlands, and fields near those woodlands. Goldsmith beetles are yellow or green in color and have a gold, metallic tint. Their elytra has irregular rows of small holes, but they do not have elytral markings. Goldsmith beetles are egg-shaped and are relatively heavy and large, ranging from 20 to 26 mm in length. Their ventral
Psephenidae water-penny beetles
This small family of beetles gets its common name ("water pennies") from the unusual shape of the larvae, which have widely expanded dorsal plates that give the animals a flat round shape, like a coin. The classification of the family is uncertain, some authorities recognize some subgroups as separate families. There are only about 263 species in 31 genera are known (Lee et alia, 2007) but this family has not received intensive study, and there are probably more species still undescribed. Members of the
Anthrenus verbasci varied carpet beetle
yellow color. Adult varied carpet beetles have wings. Varied carpet beetles are distinct from other beetles in their genus (Anthrenus) in having 11-segmented antenna and in having body scales more than twice as long as wide. They can be differentiated from the 11-segmented antennae common carpet beetles by the width and length of the scales. Full-grown larval beetles range in length from 4-5 mm and present tufts of setae. Larvae have elongated bodies with a narrow front and broad rear. The setae form light
Nicrophorus americanus American burying beetle
relationship with mites Poecilochirus. A beetle provides mites with access to food and means of dispersal, and the mites clean the beetle of microbes and fly eggs that are carried up from carrions. There are no known direct positive effects of American burying beetles on humans. There are no known adverse effects of American burying beetles on humans. American burying beetles were listed as an endangered species by U.S. Fish and Wildlife Service in 1989. They are currently considered critically endangered
Alaus oculatus eyed click beetle
about the numbers of beetles attracted to lights, and about those beetles who choose to enter houses, especially in wooded areas. This problem can be alleviated by turning lights off, replacing and improving screens over windows, and aerosol sprays (Day 1996).Click beetles include several genera in the family Elateridae. Their ability to "click" by moving their prothorax and a lobe of their prothorax has earned them their common name (Borror and White 1970). The beetles themselves eat nectar from flowers
Hippodamia convergens convergent lady beetle
beetles have been reported to eat. This makes this species a useful tool in controlling aphid populations on farms. Hippodamia convergens also eat the eggs and larvae of other insects, such as stinkbugs, asparagus beetles, and potato psyllids. Although both immature beetles and adults eat mostly aphids, during the fall when they are getting ready for hibernation, adults will feed on pollen to gain extra fat for hibernation. When there is food scarcity, it is not uncommon for coccinellids to become
Adalia bipunctata twospotted lady beetle
Native to North America (Marshall 2000). Lady beetles will live in nearly any vegetation, as long as there are aphids or other small insects to eat. Adult two-spotted lady beetles are 4-5mm long, and ovoid in shape. The head and thorax is black with yellow markings. Their undersides are black to reddish-brown; Their elytra (wing covers) are orange with one black spot on each side. The larvae are elongate, with soft bodies, and are black with yellow and white spots (they look a little like tiny alligators
Coccinella septempunctata sevenspotted lady beetle
predators, but chemical signals are also a major defense component. Coccinella septempunctata has several toxic N-oxides and alkaloids that exude from the gland between the femora and tibia. These chemicals can be released due to threats or attacks from predators and can account for up to 20% of the body weight of the beetle. These compounds are highly toxic to many common beetle predators like birds and small mammals. Spiders are also known to prey on Coccinella septempunctata larvae. Intraguild predation
Cicindela dorsalis northeastern beach tiger beetle
pupa becomes darker. The adult Cicindela dorsalis emerges through a slight hole in the dorsal portion of the pupal case, a process which requires two hours to complete. Mating occurs on warm, humid days. Female tiger beetles lay eggs individually into small depressions that will later be enlarged into burrows by the larvae as it matures. Tiger beetles are only known to produce one generation per year. Female tiger beetles have sensitive hairs on their abdomens that detect moisture content in the soil
aphids, whiteflies, mites, butterflies and moths eggs and larvae, leaf beetle eggs and larvae, and spider mites. They can be used to reduce pest populations in agriculture. Spotted lady beetles may also pollinate the plants they visit. Spotted lady flies have no known negative economic impact. Spotted lady beetles are not endangered. Coleomegilla maculata are commonly known as spotted lady beetles or 12-spotted lady beetles
populations. Hybrid offspring have an intermediate morphology; they range from blue-green in color to brown-purple with brown abdominal sterna, which contrasts with the shiny green of dogbane beetles and blue of cobalt milkweed beetles. As adults, F1 offspring mate as frequently as non-hybrids, but they cannot reproduce. Dogbane beetle males are generally less choosy than cobalt milkweed beetles. For those that live in the hybrid zone, however, males of both species are usually more choosy. Dogbane beetles
beetles carry a yeast called Kodamaea omheri on their bodies that can mimic the alarm pheromone when combined with pollen, attracting more beetles. These beetles can even recognize organic compounds in fruits, allowing them to find, infest, and eat them. Small hive beetles are primarily insectivores, eating bee eggs, bee larvae, dead bees, and the honey the bees produce throughout a colony. These beetles also feed on nectar, pollen, and fruits. Small hive beetles have rigid front wings called elytra and a
parental investment. The lifespan of red milkweed beetles has not been determined. Adult red milkweed beetles feed during June and July. They tend to be solitary. As fliers, red milkweed beetles are able to easily move around. Red milkweed beetles mostly communicate through pheromones. They use visual, tactile, and chemical senses of perception. Red milkweed beetles feed primarily on the leaves, stems, and flowers of their host plant, common milkweeds. They have also been observed feeding on horsetail
protection to the Dytiscus marginalis beetles and other water beetles by going further than just restricting collection. The Water Beetle Specialist Group and the Saproxylic Invertebrate Project are two organizations that have been hard at work fostering the education, biodiversity, and conservation of the water beetle.(Evans and Bellamy 1996
of its abdomen 270 degrees in any direction, which allows for an impressive "firing range." In effect, the beetle can spray in whatever direction the predator comes from, a decided advantage (Dawkins 1985; Eisner 2000; Salleh 1999). A member of the family Carabidae, more commonly known as the ground beetles, the bombardier beetle quite naturally shares some of the habits of its family, and like most other ground beetles tends to come out at night to prey on smaller insects. Unlike most other ground beetles
beetles lay eggs within the first two weeks of their adult life. Fourteen-spotted lady beetles do not use parental involvement when raising their young. Temperature impacts the longevity of fourteen-spotted lady beetles. Colder temperatures enable them to live for longer periods. Warmer temperatures reduce their lifespans. At 17°C, female fourteen-spotted lady beetles may live for around 120 days. At 30°C, they may live only 30 days. Fourteen-spotted lady beetles mostly live on the ground. They can fly
and partially deflexed. The eyes are oval and prominent. The wings are large and well-developed. Native dung beetles emerge mainly during late summer into fall. For the first several weeks they are in a "maturation feeding stage". A majority of beetles are in the adult stage during the winter. Ocassionally eggs are laid in the fall, which then emerge in spring. It is unclear what the exact function of food balls is in the life cycle of the Native dung beetle. While most beetles store dung in food chambers
tiger beetle larval burrow and roll them into the burrow, where they develop at the bottom and then crawl onto the tiger-beetle larva. When the tiger beetle larva begins to pupate, the bee-fly larvae consume it. Mites also parasitize tiger beetles. Ghost tiger beetles are undisturbed dune specialists and may be important environmental indicators of undisturbed habitat. There are no adverse effects of ghost tiger beetles on humans. Ghost tiger beetles have been extirpated from portions of their previous
common predators of green June beetles are blue jays. Blue jays seem to selectively feed on female beetles. Common grackles and brown thrashers also prey on these beetles. Green June beetles feed on a variety of plants. They can damage the plants from which they feed, impacting other wildlife. Green June beetles have no known positive economic importance. Adult green June beetles are a significant pest of orchards and vineyard fruits. Larvae may uproot and loosen the soil around plant roots in areas like
The horned fungus beetle, also known as the forked fungus beetle, can be found in the northeastern part of United States and eastern part of Canada. These beetles live in dying and dead tree trunks found in forest habitats. The color of horned fungus beetles ranges from black to a dark brown. There is a distinct sexual dimorphism. While both males and females have antennae, males have two horn-shaped antennae that extend forward on the head and one forked horn on the middle of the head. Females have
Like all beetles, Japanese beetles have a hard exoskeleton and chewing mouthparts (Barnes, 1987). The adult beetle is 10-12 mm long with a metallic body (usually green or copper) and bronze wing covers (Fleming, 1972). These hardened wing covers are actually modified wings called elyptra (Meglitsch andSchram, 1991).The Japanese beetle egg is white and almost translucent. It's shape is spherical and it is about 2 mm in diameter(www.ncsu.edu, 1).The larvae are white grubs with a grayish cast to them because
Parasitoid bee-flies (Anthrax) lay eggs on the substrate near a tiger beetle larval burrow and roll them into the burrow, where they develop at the bottom and then crawl onto the tiger-beetle larva. When the tiger beetle larva begins to pupate, the bee-fly larvae consume it. Approximately 7% of festive tiger beetle larvae are attacked by parasitoid bee-flies. Mites also parasitize tiger beetles. Festive tiger beetles are interesting and attractive members of sandy habitat faunas throughout much of eastern
supply in the tree, resulting in tree death. Blue stain fungus, which is distributed by mountain pine beetles alone, stops the tree from using resin to remove the beetles from its phloem. In this way, blue stain fungus and mountain pine beetles are mutualists. Signs of mountain pine beetle infestation include the presence of pitch tubes on the surface of trees in which the beetles have begun to dig egg galleries. Color of pitch tubes ranges from brown to pink or white. An increased presence of woodpeckers
mates with multiple females. Female stag beetles lay their eggs on dead trees or stumps that will provide suitable food and protection for their offspring. In temperate climates, adults only live for a single breeding season. Eggs laid by female stag beetles are supplied with a small amount of nourishing yolk, but the beetle larvae hatch quickly, and receive no additional care. Male stag beetles do not care for their offspring. Males use thier impressive manibles in defense, as well as to compete with other
the world and at most elevations. These beetles lay their eggs in wood where they hatch as larvae and spend most of their lives. Most woodboring beetles have native ranges that fall into three regions: Palearctic, Nearctic, and Oriental. However, their native ranges also include the Australian, Ethiopian, and Neotropical regions. The beetles in these regions are mostly endemic to these regions, while the beetles in the first three regions are about 50/50 native and introduced. These beetles can occur at
longevity, and production of wood products (the “galleries” they create negatively impact marketability and profit). The velvet longhorned beetle is not considered on the IUCN Red list. The velvet longhorned beetle is not classified on the United States Endangered Species Act list. The velvet longhorned beetle is not classified on the CITES appendices. The velvet longhorned beetle is not classified on the State of Michigan List. There is still research being done to find the best way to control the
asian long-horned beetles do not have any documented anti-predator adaptions. Asian long-horned beetles are detrimental to any ecosystem they inhabit. In China, approximately 40% of poplar plantations have been damaged, meaning the wood is good only for packing material. In the Ningxia Province of China, more than 50 million trees were destroyed over a three-year period because of the beetles. These beetles have the ability to significantly alter the composition of North American hardwood forests. It is
weigh up to 140 grams, the forest must provide fallen trees of adequate girth. Although the adult beetle is capable of flight it has been observed primarily in the undergrowth and the forest floor, inhabiting those areas which permanently retain moisture and provide a healthy supply of fallen fruit for consumption. Hercules beetles are some of the largest beetles and indeed, some of the largest insects alive today. The larva of D. hercules in its later instars (larval growth stages) can weigh up to 140
moult, leading to the conclusion that the time between moults could be more than five months. Very little is known about the reproductive behavior of the trilobite beetle. Wong (1996) observed a single female trilobite beetle attempting to attract a mate by lifting its abdomen and exposing the genopore. It is assumed that the female was dispersing pheromones as well. The male beetle appears to attach itself to the females gonopore through a long-curved genitalia for around five hours, before detaching and
Plagiometriona clavata, the clavate tortoise beetle, is native to the Nearctic region. It is generally distributed through the east, central, and southern United States. These leaf beetles are generally found on agricultural farms or suburban and urban gardens where solanaceous plants are grown. They can also be found sparsely in the wild where species of Solanum grow, usually in grasslands, meadows, and forests. Adults have large elytra and pronotum, creating a shield over the entire body. The head is
observed feeding on grapevine beetles, and it is likely that many other bird species also are predators of these beetles. In Texas, the remains of P. punctata have been found in nests of the pallid bat, Antrozous pallidus, suggesting that A. pallidus is another predator.In defending itself against predators, the grapevine beetle may take advantage of the bright color and slight metallic tint of its elytra. Other brightly colored, shiny beetles in the family Rutelinae have been shown to reflect polarized
Euchroma giganteum giant metallic ceiba borer
The adult beetles are found mostly on acadia branches in arid desert flats on summer days. The adult beetles are also found walking or flying around the trunks of trees. The beetles frequently visit flowers, and various other deciduous trees or large shrubs, where they feed on pollen. Adults of Euchroma gigantea usually measure between 5 to 8 cm in length, the largest of their type. The body shape resembles a bullet that is slightly flattened. The beetles have wing cases, called elytra, which are covered
Altica subplicata, the willow leaf beetle, is found north of Mexico, across the Nearctic region. It ranges from the southern most point of Texas to southern Canada from British Columbia to Quebec. The highest concentration of this species is along the Mississippi River and the Great Lakes, extending west to the Rocky Mountains. Altica subplicata thrives in sand dune habitats along the Great Lakes and on sand bars in rivers. The density of beetle populations decreases significantly with increasing distance
occurs as soon as the adult beetles are active after metamorphosis (Weber and Heimbach, 2001). These beetles can live as long as three years in the wild, but not all of them will survive until sexual maturity (occurring at 1-3 years) (Newton, 2021). As with many other beetle species, not all eggs will be fertilized or viable. Of the ones that are, some may die as eggs or larvae to disease, environmental events, predation, or developmental errors. After metamorphosis, the limiting factors become food
Rodolia cardinalis vedalia
vedalia beetle has no natural predators and so can outcompete native ladybugs which also offer important pest control benefits. Rodolia cardinalis is extremely sensitive to some insecticides such as Baythroid, commonly used on citrus crops. Global populations are strong however, and require no special conservation status. In the Middle Ages, certain species of coccinellid beetles were dedicated to the Virgin Mary and named "beetles of Our Lady." As time progressed ladybird beetles, ladybirds, or ladybugs
evaporation, which give the soil a pH of around 8.5. The areas where these beetles can be found are around lakes, ponds, rivers, streams, and shallow roadside ditches that have a high salinity. Crimson saltflat tiger beetles are around 9 to 13 mm long, with most individuals ranging from 10 to 11 mm. Along their wing covers they have three different crescent shaped markings known as maculations, that can be used to distinguish some subspecies. Most colormorphs are a shade of red, while some subspecies have
Cicindela hirticollis, commonly called the hairy-necked tiger beetle, is one of the most widely distributed tiger beetle species in North America, with its subspecies occupying more limited ranges. The subspecies Cicindela hirticollis hirticollis ranges from the southeast U.S. to New York state, and west to the southern Midwest. The subspecies Cicindela hirticollis rugifrons and Cicindela hirticollis rhodensis are present in the New England states and the upper Midwest. Cicindela hirticollis siuslawensis
present. The legs of C. sycophanta are slim and modified for running. This beetle also possesses sharp tarsal claws that facilitate crawling under stones, logs, bark, and debris. The tarsi have five segments each. Adult C. sycophanta are a brilliant golden green color with a dark blue thorax. Larvae are a polished black with brown markings on the underside. They also possess sharp projecting mandibles and a pair of bristly appendages at the hind end of the body. The beetle goes through egg, larval, and
rise to more green beetles. A possible explanation for these color morphs could be that the haze of pollution appears more brown than clear, so bronze beetles would blend in more effectively (Keinath, 2021). These beetles are effective natural predators of apple maggots (Rhagoletis pomonella) and bird cherry-oat aphids (Rhopalosiphum padi) (CABI, 2021). Additionally, they keep levels of certain weed species like the dandelion (Taraxacum officinale) in control (Sunderland, 1995). Harpalus affinis have some
Lucanus mazama, commonly known as the Cottonwood stag beetle, are found in North America, primarily in the southwest United States and southern Mexico. Cottonwood stag beetles prefer dry, temperate to hotter habitats with loose soil and decaying wood. Ideal habitat for the species is woodland areas, particularly cottonwood forests in riparian areas. Recently they have been found in wood chip beds at urban parks and playgrounds. This species is a type of stag beetle, with a mature segmented body, six legs
Japanese beetles. These two beetle species can cause considerable damage to plants in their ecosystems, and thus Scolia dubia help to keep populations under control and ecosystems healthy. These wasps have been introduced as biological control against Japanese beetles in areas where beetle populations were too abundant. Scolia dubia also consume nectar as adults, and thus may serve as a pollinator for flower species it feeds upon. This species can be an indication of grub infestation and can also be used as
Crioceris asparagi is native to both Europe and northern Asia, with the exception of China. It is an introduced species in North America, and is particularly widespread in southern Canada. It is also an agricultural pest in Hawaii. Crioceris asparagi, the common asparagus beetle, lives on cultivated and feral asparagus, in agricultural fields and grasslands. In the winter, these beetles are found in piles of woody debris and refuse, under small rocks, in piles of decaying asparagus tops, and in the loosened
reducing the destruction of foliage by 86%. Other beetles such as Lebia grandis feed on eggs and larvae of the Colorado potato beetle, while the larvae of the same species act as parasitoids on the pupae of Leptinotarsa decemlineata.There is some evidence that the Colorado potato beetle produces a toxin, leptinotarsin, that protects the larvae and adults from predation. This is evidently not sequestered from the host plant, because no sequestered alkaloids have been found. The larvae and adults also have
intermediate host. The tapeworm's eggs are passed in the rat's feces, and beetles are infected when they eat the eggs; the metacestode stage in the beetle is called a cysticercoid. The rat is infected when it eats an infected beetle. Once the egg is digested by the intermediate host arthropod, the oncosphere, a fully developed larva contained in the egg, is released into the intermediate host. Its function is to migrate to the haemocoel (body cavity) of the insect where it will grow and differentiate into
The alligatorweed flea beetle naturally inhabits southern Brazil and northern Argentina along waterways. It has been introduced to the southern United States. The alligatorweed flea Beetle is naturally restricted to waterways where the plant Alternanthera philoxeroides (the alligator weed) grows. Agasicles hygrophila require a steady temperature of 20 - 30 degrees Celsius. Adult beetles are between 4 and 7 mm long, and about 2 mm wide . Head and thorax are shiny and black in color. Adult elytra (forwings
forest edges, roadsides, fields, and vacant lots. S. elaegnifolium is also a weed-like plant that lives in many habitats. It is found throughout most of the United States. S. xanti grows in the southwestern United States in chaparrals, woodlands and forests. As their common name may suggest, adult eggplant tortoise beetles are shaped like tortoises. They are a yellowish green color with a concealed head and claws, which differentiates G. pallidula from other North American species of tortoise beetles. The
Myotis myotis mouse-eared bat
primarily feed on ground beetles such as carabids (Carabidae), but also prey on large moths and grass beetles whenever possible. M. myotis prefer feeding in open woodland with ground cover of few grasses. They may have evolved to catch ground beetles on the soil surface. However, they may select alternative preys if primary sources do not meet their requirements. They consume around 25-50% of body weight nightly. The main factor that causes decline of M. myotis populations may be human disturbance. People
Calligrapha philadelphica can be found in the eastern half of North America, in the Nearctic region. In Canada, specimens have occasionally been spotted as far west as British Columbia. Calligrapha philadelphica is found on dogwood plants in temperate forests. In areas where there is an abundance of dogwood, C. philadelphica can be found forming small colonies. This chrysomelid beetle has also been found on willow plants in areas where dogwood and willow are present together. All Calligrapha share common
