Top 20 Most Common Insects in Roy

Depending on the species, the adult Culex mosquito may measure from 4–10 mm (0.2–0.4 in). The adult morphology is typical of flies in the suborder Nematocera with the head, thorax, and abdomen clearly defined and the two forewings held horizontally over the abdomen when at rest. As in all Diptera capable of flight, the second pair of wings is reduced and modified into tiny, inconspicuous halteres. Formal identification is important in mosquito control, but it is demanding and requires careful measurements of bodily proportions and noting the presence or absence of various bristles or other bodily features. In the field, informal identification is more often important, and the first question as a rule is whether the mosquito is anopheline or culicine. Given a specimen in good condition, one of the first things to notice is the length of the maxillary palps. Especially in the female, palps as long as the proboscis are characteristic of anopheline mosquitoes. Culicine females have short palps. Anopheline mosquitoes tend to have dappled or spotted wings, while culicine wings tend to be clear. Anopheline mosquitoes tend to sit with their heads low and their rear ends raised high, especially when feeding, while culicine females keep their bodies horizontal. Anopheline larvae tend to float horizontal at the surface of the water when not in motion, whereas culicine larvae float with head low and only the siphon at the tail held at the surface.

Among the most common mosquitos in the Unites States, common house mosquito (Culex pipiens) is a ubiquitous biting pest. It has adapted to thrive in human-touched conditions and even to feed on the blood of avian species closely connected to humans, such as pigeons and doves. However, only females consume blood; the males survive on sap and nectar.

Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.

The western spotted orbweaver (Neoscona oaxacensis) has a large, round abdomen that's brown with white spots. It builds its webs in open areas, making it easy to spot. Its webs are circular like other spiders, but instead of making a stabilimentum web like other orb weavers, its webs are more sporadic and spaced out.

The eastern Boxelder Bug (Boisea trivittata) pierces and feeds on maple seeds. They are not generally considered pests unless they invade homes or destroy fruit in the process. If they do invade homes, their excrement can stain the upholstery. They are also known as the boxelder bug.

The bold jumping spider (Phidippus audax) earned that name from its ability to be sneaky and jump on their prey. Their incredible eyesight allows them to spot prey from greater distances than other spiders. Another possible way it could have earned its name is due to its mating habits. If the female approaches too quickly the male can jump away.

The eight-spotted skimmer (Libellula forensis) is identified by the eight black markings on its wings. It is occasionally confused with the Twelve-spotted skimmer that is sometimes called the Ten-spotted skimmer. You may attempt to desperately count the number of spots on these fast-moving skimmers, but the major differentiation in this one is the lack of black tips on their wings.

A particularly hated invasive species in North America, european paper wasp (Polistes dominula) is well-known for its tendency to nest on human porches and sting if approached. Nests are controlled by a dominant female queen, who lays most of the eggs. Dominance among individuals can be predicted by the shape, size and number of spots they display, with more spots signaling greater dominance within the nest.

The common Pill-Bug is a nocturnal woodlouse species that's fairly popular among hobbyists and sometimes kept as a pet. When disturbed, this small bug rolls into a ball, resembling a pill or armadillo, hence both its Latin and common English names. Compared to other Armadillidium species, this one is able to withstand drought more than any other.
