Are The Caterpillars Of Woolly Bears Invasive?

Woolly bear caterpillars are a common and well-known species that coexist harmoniously with other native species without disrupting the local ecosystem. They are the larval form of the Isabella Tiger Moth, which is rusty brown and black but not poisonous. Woolly bear caterpillars feed on leaves of hickory, walnut, ash, elm, and oak trees. Folklore suggests that woolly bear caterpillars can predict winter severity, but scientific studies have explored the validity of this belief. Researchers have found that the color variation in woolly bear caterpillars is significant.

There are eight or more species in the U. S. that could legitimately be called woolly bears due to their dense, bristly hair. Woolly bears spend the entire winter as caterpillars, seeking a good spot to overwinter in fall when temperatures begin to cool. Birds that hunt hairy caterpillars are some of the main predators of woolly bears. Parasiteic wasps can also attack woolly bear caterpillars, laying their eggs on or inside them. The legend says the coming winter will be cold if the woolly bear has a narrow, orange middle band, and warm if the band is wide. Woolly bears are most prolific in the fall when they are on the move, crossing roads and sidewalks in search of food and winter shelter.

Limantraria dyspar, an invasive plant, should be disposed of due to its invasive properties. Woolly bears are common generalist caterpillars that feed on a wide range of plants and have not been inspected for disease. They may also not have been approved for importation into the U. S. Woollybear caterpillars are not considered invasive species and may not be inspected for disease.
