Sphenophorus spp.

Billbugs belong to a group of beetles called weevils or snout beetles. Several species of billbugs attack turf. In Oklahoma, the bluegrass (Sphenophorus parvulus) and hunting (S. venatus vestitus) billbugs are most damaging to turf. Adult billbugs are gray, black or brown, and measure 3/8 inches long. They have a beak-like snout; and the snout, head, and thorax are about as long as the wing covers. Billbug grubs are white, legless with a somewhat curved body and measure about 3/8 inches long when fully grown. They have a brown head capsule and can usually be found in grass stems or thatch.
