Top 20 Most Common Insects in Nebraska

The monarch butterfly (Danaus plexippus) is the most recognizable butterfly in North America. It is best known for its appearance, but should be better known for the fact that it has a 3000-mile migration that takes the butterfly 4 generations to complete. Their diet is also a natural deterrent for predators, as they eat milkweed, a poison that induces vomiting.

A common species of mosquito, inland floodwater mosquito (Aedes vexans) is often encountered near areas containing water such as grassy pools, shallow ponds, and even wet ditches. Only the females bite humans for their blood, as males subsist upon nectar and sap. Inland floodwater mosquito is a noted carrier of diseases such as Zika virus and myxomatosis.

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.

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.

Plains floodwater mosquito has the unique ability to rapidly proliferate in floodwater, hence its name. This mosquito is both a voracious feeder and a vector, spreading diseases such as La Crosse Encephalitis with its bite. Its population spikes are directly connected to the frequency of floods, making it a species highly responsive to weather changes. Their presence offers a warning of ecological shifts and populations often serve as food for bats and birds, highlighting their dual role in ecosystem dynamics as both predator and prey.

The woodland malaria mosquito (Anopheles punctipennis) is identified with a unique wing pattern when compared to other mosquitos. Otherwise, they are known to live inside of abandoned buildings or tree stumps during the winter period, which is why they enjoy woodlands. As stated by the name, it is also a vector for malaria, which is concerning given females enjoy blood meals.

The painted lady is a migratory butterfly that spends part of the year in Northern Africa and then migrates to Europe during the warmer months. Although the adults feed on nectar from flowers, the larvae feed on the leaves of nettles and thistles.

The black Swallowtail (Papilio polyxenes) is one of the fastest swallowtails out there. With a lifespan that maxes out at 45 days, it has a limited amount of time to get a mate. As a result, courtship is only around forty seconds long. They can also put their abdomen at the top of their wings, keeping them warm during colder flights.

Red admiral (Vanessa atalanta) is a visually striking species of butterfly. Unusually territorial, males will compete for choice areas, and females will only mate with males that maintain their own territories. This butterfly is known for being particularly patient with human interactions, even to the point of perching on clothing or flesh.

The common Eastern Bumble Bee (Bombus impatiens) is one of the most important pollinator bees in North America. A decline in the bee population will lead to financial hardships for farmers and reduced food yield. Their efficiency in pollination and foraging comes from their ability to drop "traplines." These lines guide other bees to the correct path for food while informing them of depleted locations.
