Pyrrharctia isabella, the Isabella tiger moth, whose larval form is called the banded woolly bear, woolly bear, or woolly worm, occurs in the United States and southern Canada. [ 1 ] [ 2 ] It was first formally named by James Edward Smith in 1797.
Isabella tiger moths (Pyrrharctia isabella) overwinter in the caterpillar stage. They can survive freezing at moderate subzero temperatures by producing a cryoprotectant chemical. [ 13 ] The larvae of another species, Phragmatobia fuliginosa , may be found on snow seeking a place to pupate.
Being parasitoid wasps, the centrator wasp must lay its eggs inside a host for the larvae to feed and grow. The female centrator wasp deposits her eggs using her ovipositor into the larvae of Pyrrharctia isabella, which is known as the Isabella tiger moth or woolly bear caterpillar.

The isabella tiger moth belongs to the subfamily Arctiinae which has 11,000 species around the world. [2] Prior to settling in for winter, the woolly worm eats a variety of plants and then produces a kind of antifreeze which protects the creature from temperatures as low as -90 degrees Fahrenheit.
The tribe was previously treated as a higher-level taxon, the subfamily Arctiinae, within the lichen and tiger moth family, Arctiidae. The ranks of the family and its subdivisions were lowered in a recent reclassification while keeping the contents of the family and its subdivisions largely unchanged.
