Yellow Wooly Bear Caterpillars
Cliff Sadof, Extension Ornamental Entomology Specialist, Purdue
Late in the summer brings its share of late season caterpillars
showing up on trees. This late in the year most of these caterpillars
have almost completed their feeding and are unlikely to cause any
damage to the tree. The caterpillar in this photo, the yellow woolly
bear (Spilosoma virginica) were found on black walnut.
When one of these caterpillars were brought into the lab, the larva
of a parasitic wasp emerged out of the abdomen, and weaved a cocoon.
