Abstract
Sensilla on the antennae of 5 species of hepialid moths—Aenetus virescens (Hepialinae) and Wiseana cervinata, W. signata, W. umbraculata, and Trioxycanus enysii (Oxycaninae)—were examined with the scanning electron microscope. Only 4 of the 6 types of sensilla previously described from noctuid moths were observed. The arrays of sensilla on oxycanine species are not uniformly distributed, especially on males; most of the sensors on any segment are on the ‘ridge’ of the pectinations, with a sparse distribution of relatively widely spaced sensors on the rest of the cuticle. In all species examined the antennae were sexually dimorphic; this was most apparent in the differing sensilla arrays of Hepialinae and in the difference in size of the antennal pectinations of Oxycaninae.
