Furry brown and green, adult Smaller Parasa moths start their lives as short, stubby caterpillars that look more like slugs.
A type of Slug Moth, Smaller Parasa larvae are unusual in shape. It is legless, wide at the front, and has a short 'tail' at the rear. This caterpillar looks like a snail without its shell. Its brown body is bordered with pink around the bottom edges. A large hump behind the head is studded with two rows of spiny hairs along the left and right dorsal (back) side, the third set being the most obvious. They are known to feed on apple trees as well as oak, elm and dogwood.
In adults, the head, thorax, and a thick, straight band on the forewings are green. The furry legs, upper corner and bottom edge of the forewings are brown. This species is active later in the summer and into autumn in the eastern part of its range. Look for them in woodlands and deciduous forests.
