Caterpillars in Your Yard and Garden
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.
About the family
Snout and grass moths are in the Crambidae family.
