Dogwood borer (Synanthedon scitula) adults are a clearwing moth (both fore and hind wings are mostly clear), resembling a small wasp. Thorax and abdomen are dark blue, almost black with yellow bands. Mature larvae are 3/5 inch long, cream-colored with reddish-brown heads and two brown spots on the upper surface of the front thoracic segment.
