Top 20 Most Common Insects in United States
Insects, equipped with segmented bodies and versatile antennae, inhabit various ecosystems in United States, from parched deserts to vibrant rainforests. This insect diversity unfolds with varying geography and climates across the region. Whether they're seen as pests or beneficial allies, insects thrive as vital components of United States's environment. Stay tuned as we delve into the '20 most common insects in United States', showcasing these fascinating creatures and the significant roles they play.
Most Common Insects
1. Monarch butterfly
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.
2. Common house mosquito
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.
3. Inland floodwater mosquito
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.
4. Western honey bee
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.
5. Common Eastern Bumble Bee
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.
6. Multicolored asian ladybeetle
Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.
7. Cabbage white
Cabbage white (Pieris rapae) derives its common name from its habits as a caterpillar, which is a ferocious pest for cabbage, kale and broccoli farmers. In North America, it is one of the first butterflies to emerge in spring, heralding the beginning of the season.
8. Eastern tiger swallowtail
Eastern tiger swallowtail (Papilio glaucus) is among the most recognizable butterflies in the eastern United States, where it inhabits a variety of habitats. This species is diurnal and usually solitary, preferring to fly high above the ground until the time comes to mate. Caterpillars display eyespots to deter birds in between some molting phases.
9. Blue dasher
The name Pachydiplax longipennis implies that the blue dasher has long wings due to the "longipennis" section literally translating to it. But this would be misleading, as the insect does not have particularly long wings. Instead, they stick out with vibrant blue colors. The dasher part of their name may be in reference to their voracious diet, as they can eat up to 10 percent of their body weight daily.
10. Eastern pondhawk
The eastern pondhawk (Erythemis simplicicollis) has much in common with American fishermen, they love living near the sides of ponds. They are a beautiful insect that is easy to distinguish when it comes to different genders. Females are bright green with bands around the abdomen and the males are bright blue with a green face.
