Turfgrass and Insects

Armyworms (fall)

Young larvae begin to feed on tender foliage. Feeding injury by the first two instars causes skeletonized foliage. The third through sixth instars consume all of the plant. When populations are high, feeding produces circular bare areas in turfgrasses. Treatments should be applied after midday, before nighttime feeding. This several generations per year.
