Hag moth caterpillar

Phobetron pithecium


This bizarre looking caterpillar not only has a great defense in camouflage and mimicking, but it also has stinging hairs that are very nasty. Its larva is known as the monkey slug. See it's movements in video:


Spotted on a trail thru a hardwood forest next to Grassy Lake at Bell Slough.


Larvae eat a variety of deciduous trees and shrubs, such as apple, ash, birch, cherry, chestnut, dogwood, hickory, oak, persimmon, walnut, and willow.
