Top 20 Most Common Insects in Missouri
Insects, complex creatures with distinctive characteristics, flourish in diverse habitats within Missouri. Varying geographies across the region significantly influence insect diversity. These organisms, while oftentimes seen as pests, play pivotal roles in maintaining our ecosystem and contribute positively to agriculture. Their presence in Missouri speaks volumes of the state's diverse environments, testifying to the essential balance in nature. Stay tuned for our top 20 most common insects in Missouri.

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. 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.

3. Brown-belted bumble bee
The brown-belted bumble bee (Bombus griseocollis) can be distinguished from other bumble bees because of the brown belt on its abdomen. It's often found in urban landscapes, near sunflowers, thistles, and milkweed. The males often fly very high in search of females, and they've even been spotted at the top of the Empire State Building.

4. 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.

5. Eastern Carpenter Bee
The eastern Carpenter Bee (Xylocopa virginica) is considered a pest and a benefit in the same body. It has earned its pest status from its ability to tunnel into human-made structures and weaken them. They can also stain their excrement on the building as they leave the tunnel. Their benefits as pollinators heavily outweigh any damage they do to structures.

6. Lone star tick
The lone star tick (Amblyomma americanum) has a white dot on its abdomen. This bloodsucker has a taste for turkeys, giving it the nickname "turkey tick." They do not tend to be picky eaters, as they do latch onto humans as well. Humans that have been bitten by this often have Southern Tick Associated Rash Illness (STARI). Symptoms such as fever, headache, and joint pain are resolved quickly using antibiotics.

7. Two-spotted bumble bee
The name of two-spotted bumble bee (Bombus bimaculatus) comes from the two yellow spots found on its abdomen. Where other bees are on the decline, this one's population remains stable. For the first day of a young male's life, they are unable to fly. As a result, they pump their abdomens against the larva in order to generate heat flow.

8. Ligated furrow bee
The ligated furrow bee (Halictus ligatus) is a type of sweat bee that has a complex social structure. In the north, short warm times appear to contribute to greater stress as queens have a more difficult time controlling their workers. In warmer regions, colony size is bigger and there is less need to grip about, resulting in an easier time for queens keeping their reign.

9. 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.

10. 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.
