 Other arthropods may make use of the antlion larva 's ability to trap prey . The larva of the Australian horsefly ( Scaptia muscula ) lives in antlion pit traps and feeds on the prey caught , and the female chalcid wasp ( Lasiochalcidia igiliensis ) purposefully allows itself to be trapped so that it can parasitise the antlion larva by ovipositing between its head and thorax .
