Abstract：Antennal morphology and sensilla of Bombus hypocrita workers were observed under scanning electron microscopy. The results show that the antenna is made up of three parts； scape， pedicel and a 10 segmented flagella，the respective lengths of which were (2 099.40±112.26) μm， (212.86±12.51) μm and (3 861.43±137.86) μm. 11 types of sensillum were observed on the antennae； sensilla placodea， sensilla ampullaceous， sensilla campaniformia， sensilla basiconca， sensilla coeloconica， sensilla trichodea， sensilla chaotic， budlike sensilla， fingerlike sensilla，sensilla margin and setae. This is the first report of budlike and fingerlike sensilla in the Hymenoptera.
