Abstract：In order to understand the overwintering situation of Streltzoviella insularis larvae,the overwintering investigation was carried out on Streltzoviella insularis larvae the distribution of overwintering sites,the postures of overwintering larvae and the head orientation were observed.The results showed that the 5th and 12th instar larvae overwintered for first time,respectively.The body weight of non-diapause larvae was larger than that of diapause(overwintering)larvae The overwintering larvae built oval chambers with dung,and 78.3％of the chambers were located at the top,14.6％at the side of the worm tunnel,and 7.1％in the worm tunnel.The wintering posture of larvae in a chamber was assumed as,87.4％of the larvae in the shape of"1",8.2％in the shape of"L"and 4.4％in the shape of"C",97.1％of the larvae had their heads down when overwintering.
