Ptecticus
soldier flies
Ptecticus is a large genus of soldier flies (Stratiomyidae: Sarginae) comprising at least 150 described species worldwide, with roughly 40 species documented from the Old World alone as of 2000. Adults display variable body coloration—yellow, brown, or black—with abdominal transverse stripes, dusky wings, and often translucent second abdominal segments. A well-developed inner projection on the second antennal segment characterizes most species. The genus exhibits wasp-mimicry in appearance and behavior. Larvae are broad, flat, segmented maggots found in fermenting fruit and rotting vegetal material.
