• Sphenophorus venatus

  hunting billbug

  Sphenophorus venatus, commonly known as the hunting billbug, is a weevil species in the family Dryophthoridae. It is native to North and Central America, with established populations in parts of Europe including Spain and Corsica. The species is a documented pest of turfgrasses and forage crops, with different subspecies showing host preferences: S. v. vestitus affects zoysiagrass, while S. v. confluens has been recorded as a pest of orchardgrass. Adults and larvae feed on grasses, with larvae causing damage by boring into stems and roots. The species uses volatile organic compounds from host plants and conspecifics for dispersal and host-finding, with males attracted to Cynodon dactylon and females attracted to male conspecifics.
