Features
  • Named 'armyworm' because they move in large, cohesive groups across fields, marching like an army to find new food sources
  • Caterpillars are often green, brown, or black with stripes along their sides. Usually have a characteristic inverted 'Y' mark on their head
  • Voracious feeders on leaves and stems. Often hide in the 'whorl' of corn or at the base of grasses during the day
  • Can skeletonize leaves or consume entire seedlings overnight. Damage often appears as large, ragged holes or complete defoliation
  • Moths lay clusters of fuzzy eggs on leaves. Caterpillars grow through several stages (instars) before pupating in soil. Fast lifecycle in warm weather
  • Caterpillars grow up to 30-40 mm long. Moths have wingspans of about 35 mm
  • Highly active at night. Populations can 'explode' after heavy rains or in specific seasonal windows
  • Major pests of corn, rice, sorghum, sugarcane, turf grass, and various vegetable crops
  • Use pheromone traps for monitoring. Early detection is critical as they consume more as they grow larger
  • Treat with Bacillus thuringiensis (Bt), neem oil, or beneficial nematodes. In large outbreaks, specific caterpillar-focused insecticides are used
