Yikes! These monsters can grow up to 6 inches long (about the size of a hot dog). Everything about them — from their startling turquoise-green bodies arrayed with black spikes to their prickly orange horns — screams, "Be afraid … be very afraid!" Even chickens, which rarely turn down caterpillar chow, are known to flee when they see one of these bad boys crawling by.
Turns out it's all a ruse. These giants, found in eastern U.S. forests, are about as gentle as they come. After feasting on the leaves of hickory, ash, persimmon, sycamore and walnut trees, they burrow a few inches into the ground in late summer. (They're one of the few moth caterpillars that don't spin cocoons.) The following summer, they emerge as ravishing orange, gray and cream-colored regal moths (below), one of North America's largest with an impressive 6-inch wingspan.
