This white-marked tussock moth caterpillar was taking a walk on the back gate so I grabbed a leaf for him and set him on a post. I think he is just delightful, every time I see one I think of the little truck that sweeps the streets in town. Take a larger look at him and see those brushes on his lower sides. He has a lot of interest going for him at this stage of his life, as a moth he is a dark gray with tan and black mottling. He feeds on the foliage of trees and shrubs and will pupate in a cocoon spun of silk and hair attached to bark, tree branches or other supports.
