 Antlion larvae are capable of capturing and killing a variety of insects and other arthropods , and can even subdue small spiders . The projections in the jaws of the larva are hollow and through this , the larva sucks the fluids out of its victim . After the contents are consumed , the dry carcass is flicked out of the pit . The larva readies the pit once again by throwing out collapsed material from the center , steepening the pit walls to the angle of repose .
