Biology. Flies of this species ( Fig. 7 A–D ) were observed in Xishan, Kunming, Yunnan Province , China by Yong Wang in the autumn of 2018. The climate there was damp and foggy. The collection site was located at the top of Xishan Mountain on a roadside. One side of the road was very close to a dense forest. The flies were found and collected on leaves of an invasive plant, Ageratina adenophora , where sugar water had been sprayed on leaves. So, it was assumed that the flies had been lured from the forest beside the road by the sugar water.
