Pyrrharctia isabella, commonly known as the Virginia tiger moth, is a species of moth found primarily in North America. It belongs to the family Erebidae and is recognized for its striking appearance, featuring a yellow or orange body with black spots. The wingspan of this moth typically ranges from 3 to 4 inches. The larvae of Pyrrharctia isabella, known as woolly bears, are covered in dense, bristly hairs and are often black or brown. These caterpillars are known for their ability to survive cold temperatures, entering a state of dormancy during winter. They eventually transform into adult moths in the spring, contributing to the ecosystem as pollinators.
