Tent caterpillars overwinter in a silvery-black egg mass on a wild cherry tree. In the early spring they hatch, crawl to a fork in the branches, and begin to spin a silken nest. They remain in the nest during the day and then crawl out to eat the leaves of the tree at night. Since wild cherry leaves contain cyanide it is likely that the caterpillars are poisonous if eaten by birds. By the way, the little black dots in the nest are not "caterpillar eggs" as some people think (caterpillars are the larval stage of moths and butterflies, they can't lay eggs). The dots are called "frass" (a.k.a. "poop"!).
