Swift Moth Larvae (Ghost Moths, Hepialidae)
Large soil-dwelling larvae feeding on roots and crowns, causing severe wilting.
Swift moth or ghost moth larvae are large, pale caterpillar-like soil pests found in turf, ornamentals, and container-grown crops. They feed at night on roots and crowns, causing rapid wilting and collapse. Control relies primarily on entomopathogenic nematodes (Steinernema carpocapsae and Heterorhabditis bacteriophora), ideally applied during warm soil conditions. Cultural reduction includes removing dense thatch and improving drainage.
