Named for their transluscent skin, glassy cutworms can be a singificant pest of corn, soybeans, grains, and other crops. Cutworms get their name from their practice of chewing on seedlings at the soil surface, cutting the plant off at its base.
Larvae are white or grey in color with transluscent skin and an orange or brown head. They grow up to 1.5" in length.

Similar to other cutworms, Glassy cutworms feed on leaves and may also cut plants off at the base, leading to stand loss and reduced yield.
