Top 20 Most Common Insects in Baraboo

Mythimna unipuncta, the true armyworm moth, white-speck moth, common armyworm or rice armyworm, is a nocturnal agricultural pest belonging to the family Noctuidae. This moth is also commonly referred to by the scientific name Pseudaletia unipuncta. The species was first described by Adrian Hardy Haworth in 1809. Mythimna unipuncta is found in the Americas and in parts of Europe, Africa and Asia. Its original distribution is North and South America. It has been introduced to other places from there. They are known as armyworms because the caterpillars move in lines as a massive group, like an army, from field to field, damaging crops. The true armyworm has a distinct migration pattern in which they travel north in the spring and south in the fall to ensure that mating occurs in a favorable environment in the summer. While progressing through the life cycle stages of egg, larva, pupa, and adult, this species must avoid attack from predatory bugs, birds, wasp and fly parasitoids, and bacterial and fungal diseases. As polygamous insects, females release sex pheromones and choose multiple males as mates. The production and release of the pheromones are influenced by temperature, photoperiod, and the juvenile hormone. Hearing is an important sense for the true armyworm, necessary for mating and evading bat predation.

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.

Hypena scabra, the green cloverworm or black snout, is a moth of the family Erebidae. The species was first described by Johan Christian Fabricius in 1798. It is found in North America from Canada south to Florida and Texas. It has also been reported from Great Britain. The wingspan is 25–35 mm. Adults are on wing from March to November or all year round in warmer regions. There are multiple generations per year. The larvae feed on low-growing legumes, including alfalfa, bean, clover, pea and soybean. They also feed on woody legumes such as false indigo and locust. Other reported hosts include birch, cherry, corn, elm, hackberry, New Jersey tea, poplar, ragweed, sida, strawberry and willow.

The widow skimmer (Libellula luctuosa) is a large insect that grows to be incredibly large with a bulbous head and body. As they age, they are known to grow whitish, much like our grandparents' hair. They live in the water until their final molt, where they reveal their wings, it is at this point it reveals why it has part of a group called the king skimmers.

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.

The northern Paper Wasp (Polistes fuscatus) has a complex society that is dominated by one queen. The first children that a queen gives birth to are infertile females, giving them the regular job of maintaining the nest. Much like human societies, northern Paper Wasps pamper their youth. There are no nursing homes for the elderly.

Agrochola bicolorago, the bicolored sallow or shield-backed cutworm, is a moth in the family Noctuidae. The species was first described by Achille Guenée in 1852. It is found in the eastern half of the United States (except southern Florida) and Canada. The wingspan is 28–38 mm. Adults are on wing from August to December in the south and from September to November in the north. The larvae feed on cabbage, cherry, crabapple, dock, elm, grass, maple, peach, plum, oak, tobacco and willow.

The japanese Beetle (Popillia japonica) was introduced to the Americas from a tourist's car in Nova Scotia. This beetle has been limited in its ability to fully infest the environment, but cannot be fully eradicated. A swarm of them have been known to strip an entire peach tree in a matter of minutes.

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.

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.
