Caterpillars in Your Yard and Garden
Garden webworm
Snout and grass moths
Garden webworm caterpillars (Achyra rantalis) are present from late spring to fall. They produce two to three generations per year.
Full-grown caterpillars are 0.5 to 0.75 inch long and have a yellow-brown head and a yellow-green to green body. The body is characterized by distinct black spots on each segment, six spots occurring on each abdominal segment, and a pale-green middorsal stripe. Host plants include a variety of vegetables, field crops, and weeds. Severely damaged plants are covered with silken webbing.
