Pelecinus polyturator (Drury)

(Insecta: Hymenoptera: Pelecinidae)

Pelecinus polyturator are endoparasitoids of soil-dwelling beetle larvae, particularly white grubs (Phyllophaga spp.).

Adults exhibit sexual dimorphism: Females, at 51 to 62 mm in length, are about four times longer than males. Their distinct, narrow abdomen is about five times as long as the rest of their body. Hind wings measure about one-third the length of the forewings.

Adults feed on plant nectar. Females reproduce by parthenogenesis, or reproduction from unfertilized eggs.

Pelecinus polyturator is commonly found in Florida.
