Top 20 Most Common Insects in Torrington

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. Mourning cloak

The state insect of Montana, mourning cloak (Nymphalis antiopa) owes its name to a visual comparison with a girl who, disliking mourning, allows a few inches of color to show from under her mourning garb. Among the longest-lived butterflies, individuals may persist for as long as eleven to twelve months. It is a powerful flier, with vagrants often found many miles from the usual migration paths.

3. 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.

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. 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.

6. 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.

7. Gypsy moth

The gypsy moth (Lymantria dispar) spends nearly its entire life on the same host tree, stripping leaves off of it. However, they will occasionally fly as a colony from one host tree to another. They are commonly recognized by their fuzzy larvae, which have dark bodies with red and blue spots. The adults are usually a pale brown color though.

8. Spicebush swallowtail

The spicebush swallowtail (Papilio troilus) is a butterfly with an extreme love for plants in the Lauraceae family, such as spicebushes. Their preference is so strong that an experiment proved they would rather die than choose another host. Their two subspecies, *T. troilus *troilus and *T. troilus *ilioneus, differ based on location. The *T. troilus *ilioneus has more bluish spots and prefers redbay and swampbay plants.

9. 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.

10. Isabella Tiger Moth

The isabella Tiger Moth (Pyrrharctia isabella) grows into the Isabella Tiger Moth. In folklore, the amount of brown on their band is said to determine the length of the upcoming winter. Over the winter it freezes completely. It prevents the damage of tissue by producing a liquid that preserves the tissue.

11. Eastern Tent Caterpillar

The sociable eastern Tent Caterpillar likes to enjoy gatherings within their nests in the trees where they rest. These caterpillars build a communal tent soon after they hatch, and together work to expand it after coming home each day from feeding. When they feel threatened, colonies of eastern Tent Caterpillar will all thrash about together to create a moving mass of bodies, scaring off timid predators.

12. Common whitetail skimmer

Common whitetail skimmer has black bands on its translucent wings which make it easy to identify. The common whitetail skimmer is found throughout North America and serves a vital ecological purpose. The dragonfly’s compound eyes provide it with a 360-degree field of vision, allowing it to spot prey like spiders and other nuisance insects.

13. 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.

14. Pearl crescent

The pearl crescent (Phyciodes tharos) is an orange butterfly that lives in open areas that are generally moist and sunny. These butterflies are attracted to puddles, and the males will often fight with other male butterflies that land near the same puddle. However, females are not as aggressive and prefer to stay in groups.

15. Silver-spotted skipper

The silver-spotted skipper (Epargyreus clarus) constructs a series of nests throughout its development that depends on its growth stage. Its caterpillar form is considered a major homebody, as they rarely leave the spot they call home. When they are adults, males perch on high branches in order to claim and defend favorable territory. Unusually, silver-spotted skipper adults never visit yellow flowers.

16. Great spangled fritillary

The great spangled fritillary (Speyeria cybele) is a beautiful butterfly that is orange in color and has a variety of spots on its body like a leopard. Females tend to be a bit darker than their male counterparts. Their caterpillars are black with orange spots and often caught feeding on violets.

17. 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.

18. Red admiral

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.

19. 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.

20. Black Swallowtail

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.
