Four instars of M. mongolica （Distant） were preliminarily determined using Dyar＇s rule and a regression analysis of the head width of nymphs, combined with the comparative morphology of antennae of different stage nymphs and adults. The antennae of nymphs in different instars and adults show great morphological variations. The numbers, types and distribution of antennal sensilla in nymphs and adults of M. mongolica are significantly different, which should be closely related to the niche changes of the nymphs and adults, and provide implications for the development stages of this cicada.展开更多
