Herpetogramma phaeopteralis, commonly known as the dark sod webworm, is a species of moth in the family Crambidae. It was described by Achille Guenée in 1854. [1]
Sod webworms have a bivoltine life cycle with four stages: egg, larva, pupa and imago (adult). They overwinter as larvae in their final or penultimate instar in the thatch or soil. With the coming of warmer weather, the larvae will pupate, and moths will appear in late spring or early summer. The first generation of eggs is laid in June, with ...
Fall webworms experience behavioral thermoregulation. [2] [16] The fall webworms' self-created web (which is where the fall webworms live) is able to trap heat. [2] [16] Due to this, the fall webworm (which is an ectotherm) is able to maintain a warm temperature of about 40-50 °C, which allows the larvae to grow and develop faster.
Predators include birds and other insects. Birds often eat the egg-laden bodies of female bagworms after they have died. Since the eggs are very hard-shelled, they can pass through the bird's digestive system unharmed, promoting the spread of the species over wide areas. [4] A bagworm begins to build its case as soon as it hatches.
