The Pitfall Trap of the Australian Ant-Lion Callistoleon-Illustris (Gerstaecker) (Neuroptera, Myrmeleontidae) - an Evolutionary Advance

Abstract

The Australian ant-lion Callistoleon illustris (Gerstaecker), constructs a unique pitfall trap with trenches radiating from the pit. This development, hitherto unrecorded, is documented and discussed and the larva is described and illustrated.
