Abstract

Antlions (Neuroptera) are a group of sit-And-wait predator insects, with some species further specializing in digging conical pit-Traps in the ground in order to catch prey. Studies on antlions' predators are scarce with only few generalist predators known to feed on them. Here we report for the first time on field observations of antlions' predation by three scorpion genera. We suggest that scorpions may be common predators of antlions, at least in the hyper-desert environment of southern Israel. The effects of predation risk on the behavior of sit-And-wait and particularly on trap-building predators received little attention in the literature. In light of our observations, we posit that predation risk must be taken into serious consideration in future research of antlions in particular, and sit-And-wait predators in general.
