Abstract

Sensilia on the sexually dimorphic antennae of the blister beetle, Meloe campanicollis, were primarily sensilla chaetica with scattered socketed and non-socketed sensilla basiconica. Forked chaetifonn sensilla on the female's first segment are displaced by the antennal socket rim when the male grasps and lifts her antennae with segments 5 to 7 of his antennae. Segments 5 to 7 lack dense sensilla chaetica and have only patches of shorter sensilla. The segments also contain a high density of epidennal gland ducts compared to other segments. Maxillary palpi apices were similar in males and females, but the female's labial palpi contained fewer narrow and many more short, broad sensilla basiconica than the male·s.
