Abstract: scanning electron microscopy of the antennae of the Yulong ghost moths Hepialus yulongensis was observed.The form of the antennae,the sensillar types,and distribution of the various sensilla were examined.The antennae of Hepialus is filiform with scape,pedicel and 21-27 flagellar segments.The antennae of both sexes are of 2.3-2.7 mm length.The scape is longer than the following segments.The cuticle of the antenna lacks the reticulation of raised ridges.Six types of sensilla found on the antennae of both male and female include sensilla trichodea,sensilla chaetica,sensilla coeloconica,sensilla basiconica,sensilla squamiformia and Bǒhms bristles.Moreover,sensilla campaniform occur on the antennae of male moths.The sensilla trichodea are further subdivided into two types (designated A and B).Bǒhms bristles occur mainly on the scape,pedicel,and apical segment.The gradual increase in the number of sensillum coeloconicum along the base of flagellar segments and the decrease near the tip.There are two morphological types of the sensilla coeloconica include the center peg of long and short pattern.The sensilla coeloconica of both types lack the inward slanting fringe pegs in the depressed periphery.
