Abstract: Most of the pit-building larvae of antlions display an interesting behavior of pit construction by digging sand and building it in a conical shape. The larva then sits at the apex, waiting for the prey to fall down the slope of the funnel. Vibrations detect the prey in the sand, which is used as a cue to orient and throw sand to knock down the prey. The sensory structure involved in this biological function is analyzed in the current study. The antenna and labial palp have a small number of sensilla meant for chemoreception and possibly hygro-reception. Eyes appear reduced with only six stemmata on a tubercle. In keeping with the subterranean mode, the sensilla chaetica (SC) on the 'jaws' are stunted, and sensilla trichoid are lacking. An assembly of four campaniform sensilla at the base of the jaws may provide sensory feedback during sand tossing and feeding. The antenna that lacks hairs on its antennomeres is remarkably long for an insect larva. Thus larvae have limited chemosensory capabilities compared to adults. The mechanoreceptors sensilla chaetica and antennae may help to locate prey. Graphical abstract: ![]() |
