We have examined antennae of both sexes of Tineola bisselliella to make an inventory of the antennal sensilla. We distinguished two types of sensilla trichodea, two types of sensilla basiconica, and sensilla auricillica, chaetica, coeloconica, styloconica, and campaniformia, Böhm's bristles, and squamiform structures. The same types of sensilla are present in both sexes. Numbers of sensilla chaetica, styloconica, and coeloconica and Böhm's bristles do not differ between the sexes. Significant differences in number and distribution of sensilla trichodea, basiconica, and auricillica were found between females and males over the whole length of the antenna.
