The antennal sensilla of Endoclita davidi,one primary host of Ophiocordyceps xuefengensis,were observed and described with the scanning electron microscopy( SEM). The results indicated that the antennae of both female and male moths were plumose.Seven types of sensilla were found,including sensilla trichodea,sensilla chaetica,sensilla basiconica,sensilla coeloconica,sensilla squamiformia,sensilla placodea and Bhm bristles. Sensilla chaetica,sensilla basiconica,sensilla coeloconica and sensilla placodea were only distributed on the flagellum; sensilla trichodea were distributed on the scape and flagellum; Bhm bristles were distributed on the base of the scape and pedicel. Most of the sensilla squamiformia were distributed on the flagellum and were largest in terms of volume. No significant difference was observed between the male and female in the type and distribution of the antennal sensilla.
