Bombus Pensylvanicus
''Bombus pensylvanicus'', the American bumblebee, is a threatened species of bumblebee native to North America. It occurs in eastern Canada, throughout much of the Eastern United States, and much of Mexico.Hatfield, R., et al. 2015''Bombus pensylvanicus''.The IUCN Red List of Threatened Species. Downloaded on 09 March 2016. Once the most prevalent bumblebee in the southern United States, populations of ''Bombus pensylvanicus'' have decreased significantly in recent years, including in its scientific namesake state of Pennsylvania, where its numbers are considered critically low. Overall, the population dropped nearly 90% in just the first two decades of the 21st century. ''Bombus pensylvanicus'' tends to live and nest in open farmland and fields. It feeds on several food plants, favoring sunflowers and clovers, and functions as a pollinator. Taxonomy and phylogenetics ''Bombus pensylvanicus'' belongs to the order Hymenoptera (consisting of ants, wasps, bees, and sawflies), the f ...

Hanover County, Virginia
Hanover County is a County (United States), county in the Commonwealth (U.S. state), Commonwealth of Virginia. As of the 2020 United States census, 2020 census, the population was 109,979. Its county seat is Hanover, Virginia, Hanover. Hanover County is a part of the Greater Richmond Region. History Located in the western Tidewater region of Virginia, Hanover County was created on November 26, 1719, from the area of New Kent County, Virginia, New Kent County called St. Peter's Parish. It was named for the Electorate of Hanover in Germany, because King George I of Great Britain was Electorate of Hanover#Electors of Hanover, Elector of Hanover at the time. The county was developed by Planter (American South), planters moving west from the Virginia Tidewater region of Virginia, tidewater, where soils had been exhausted by tobacco monoculture. Hanover County was the birthplace and home of noted American statesman Patrick Henry. He reportedly married Sarah Shelton in the parlor ...

Bombus Morio
''Bombus morio'' is one of the few bumblebee species found in South America. These bees reside mainly in the forests of Brazil, nesting on the surface of the ground. They are one of the biggest species of bumblebee and are important pollinators. They are one of the few species of bees that exhibit buzz pollination to collect pollen from the flowers. Taxonomy and phylogeny In South America, most of the bumble bees are distributed among the Andes mountains and in temperate regions, with a few species being observed in the warmer lowlands. Out of these bumble bees, only six are known to exist within Brazil, and they all belong in the same subgenus of '' Fervidobombus''. Five of these six are very closely related, but the sixth, the ''Bombus morio'', belong to a distinctive clade. Phylogenetic analysis has shown that the ''Bombus morio'', are exclusively distinct. Habitat There are known to be around 250 ''Bombus'' species. Most of these species occur in the northern climate zones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallophora Bomboides
''Mallophora bomboides'', also known as the Florida bee killer, is a Predation, predaceous species of robber fly of the family Asilidae that feeds primarily on bumblebees. ''M. bomboides'' is a noteworthy instance of Batesian mimicry given its close resemblance to its prey, the bumblebee. These bees are typically found in the Eastern and Southern regions of the United States like South Carolina and Florida. Physical description ''M. bomboides'' typically have three basal Abdomen, abdominal Tergum, tergites densely covered with yellow hairs. The fourth and fifth tergites have black hairs, and the final two segments have pale hairs. The ventrum of the abdomen is adorned with yellow hairs. The average body length of ''M. bomboides'' is about 25 mm. Distribution Geographical distribution ''M. bomboides'' occurs in the southeastern United States in states including North Carolina, South Carolina, Georgia (U.S. state), Georgia, Florida, Alabama, and Mississippi.

Asilidae
The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking Insect mouthparts#Hypopharynx, hypopharynx. The name "robber flies" reflects their expert predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and catch their prey in flight. Overview The Asilidae are a family in the Order (biology), order fly, Diptera, the true flies. The common name for members of the family is robber flies, a name first suggested in 1869 by Alpheus Spring Packard, Alpheus Packard based on the German "Raubfliegen" (predatory flies). The Asilidae are Cosmopolitan distribution, cosmopolitan, with over 7000 described species. Pierre André Latreille, Latreille was the authority for establishing the family in 1802. The Asilidae, together with Bombyliidae and Therevidae, are the most representative families of the superfamily of Asiloidea and they for ...

Ambush Bugs
Insects in the subfamily Phymatinae are commonly called ambush bugs after their habit of lying in wait for prey, relying on their superb camouflage. Armed with raptorial forelegs, ambush bugs routinely capture prey ten or more times their own size. They form a subgroup within the assassin bugs. Description Phymatinae are long. The most distinguishable trait of this group is the presence of pronounced raptorial forelegs. In '' Phymata'', the scutellum is triangular and shorter than the pronotum. In '' Macrocephalus'', the scutellum is narrow and rounded, extending to the tip of the abdomen. Phymatinae normally have a large fore femur and clubbed antennae. The forewing membranes sometimes lack distinct cells. The antennae have four segments. There are two ocelli. The beak has three segments. The tarsi also have three segments. The rear half of the abdomen expands beyond the edges of the wings. Compared to classic assassin bugs, ambush bugs are shorter, stouter, more colo ...

Crab Spiders
The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders. Description Members of this family of spiders do not spin webs, and are ambush predators. The two front legs are usually longer and more robust than the rest of the legs. The back two legs are smaller, and are usually covered in a series of strong spines. They have dull colorations such as brown, grey, or very bright green, pink, white or yellow. They gain their name from the shape of their body, and they usually move sideways or backwards. These spiders are quite easy to identify and can very rarely be confused with Sparassidae family, though the crab spiders are usually smaller. Etymology Spiders in this family are called "crab spiders" due to their resemblance to cra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aposematic
Aposematism is the Advertising in biology, advertising by an animal, whether terrestrial or marine, to potential predation, predators that it is not worth attacking or eating. This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous animal coloration, coloration, sounds, odours, or other perception, perceivable characteristics. Aposematic Signalling theory, signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. ...

Haplodiploidy
Haplodiploidy is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. Haplodiploidy is sometimes called arrhenotoky. Haplodiploidy determines the sex in all members of the insect orders Hymenoptera ( bees, ants, and wasps) and Thysanoptera ('thrips'). The system also occurs sporadically in some spider mites, Hemiptera, Coleoptera ( bark beetles), and rotifers. In this system, sex is determined by the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female, and an unfertilized egg develops as a male. This means that the males have half the number of chromosomes that a female has, and are haploid. The haplodiploid sex-determination system has a number of peculiarities. For example, a male has no father and cannot have sons, but he has a grandfather and can have grandsons. Additionally, if a eusocial-insect c ...

Bombus Sonorus
''Bombus sonorus'', commonly known as the Sonoran bumble bee, is a species of bumble bee in the family Apidae. It is found in Mexico and southwestern North America. Although it has often been categorized as a subspecies of ''Bombus pensylvanicus'', it has since been shown to not hybridize with B. pensylvanicus over a broad area of geographic overlap, confirming its status as a distinct species. Description Female ''B. sonorus'' is recognized by having the thoracic hairs yellow on the pronotum, anterior portion of scutum, and scutellum resulting in a black band between the base of the wings. Additionally, the first three abdominal segments (T1-T3) are entirely yellow. Males are similar, but have T1-T4 yellow. The shade of yellow is deep golden color. It can be confused with the yellow form of '' Bombus crotchii'' and with '' Bombus nevadensis''. It is known to collect pollen from Gossypium, Viguiera, Helianthus, Linaria, Chrysothamnus, and Kallstroemia flowers. These bumblebees g ...

Bombus Transversalis
''Bombus transversalis'' is a bumblebee specifically native to the Amazon Basin. It is most notable for its surface-level colonies which are built by the workers on the rainforest floor. Unlike its relatives, ''B. transversalis'' is able to thrive in a humid climate and fend off a wide range of predators because of its resilient nests. While there is great deal of information pertaining to their nests and foraging abilities, there is much more to be learned about relationships within the colony and life cycle of the bee. Taxonomy and phylogenetics ''Bombus transversalis'' is in the order Hymenoptera, which consists of bees, ants, wasps, and sawflies. It is in the family Apidae and in the genus ''Bombus''. Most ''Bombus'' live in temperate climates and build their nests underground from abandoned tunnels. ''Bombus transversalis'' has adapted to tropical climates and builds its nests on ground surface. It is classified under the subgenus '' Thoracobombus''. An example of a related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrill Carder Bee
''Bombus sylvarum'', the shrill carder bee or knapweed carder-bee, is a species of bumblebee with a wide distribution across Europe, east to the Ural Mountains, and north to Great Britain, Ireland, and southern Scandinavia. It is called the "shrill carder" because the pitch of its buzzing is more shrill than other bees and it is a carder bee – making its nest by carding material into a fabric. Description It is a small bumblebee; queens are long and female workers are . It is mostly pale yellowish in colour with a black band across the thorax, two black bands across the abdomen, and an orange tip to the abdomen. It flies rapidly and queens produce a high-pitched buzz. Behaviour The flight period lasts from about April to September. The queen bee emerges from hibernation in the spring. She makes a nest on or slightly below the surface of the ground among open vegetation. An old mouse or vole nest may be used. By summer, the nest may contain around 100 worker bees. Each nest r ...

Bombus Ruderarius
''Bombus ruderarius'', commonly known as the red-shanked carder bee or red-shanked bumblebee, is a species of bumblebee found in Eurasia. Description Though sometimes mistaken for ''Bombus lapidarius'', ''Bombus ruderarius'' varies slightly in appearance from ''B. lapidarius'' in several ways. ''Bombus ruderarius'' is a relatively small bumblebee with a wide abdomen, an oblong face, and a fairly long tongue. The queen has an average length of and a wingspan of , while the other castes are somewhat smaller; the workers have an average length of and the males . Their colour is prominently black, with a red tail; among males, however, a lighter form exists with yellow-green hairs on the thorax and the first two terga (abdominal segments). The corbicula (pollen basket) on the hind legs of females (queens and workers) is covered with yellow-red hair. Ecology The nest is constructed of grass or moss, on or slightly below ground, and typically contains 50 to 100 workers. Often, ...
