 Owlfly larvae are ambush predators, and sequester themselves at the soil surface, in ground litter, or on vegetation, sometimes covered with debris, and wait for prey, which they seize with their large, toothed mandibles.They resemble antlion larvae, but have an elongate, sometimes finger-like appendage on the side of each segment called a scolus-like process.In some genera, larvae actively place sand and debris onto their dorsum as camouflage.
