Our yard has been full of woolly bears this year. Lately, it seems as if they are everywhere I look. They are among the most recognized and well-loved caterpillars. I can see why- they are adorable. If there is a survival benefit to being a fuzzy little guinea pig mimic- then these little creatures have it.

Festivals are held in their honor. They are credited with predicting winter weather. Even other insects seem to like them…
