Vestalis gracilis

There are quite a few species of Calopterygidae damsels in Vietnam. One of the commoner ones is Vestalis gracilis, which I encountered regularly around Ba Be National Park (in July), where it could be found along all sorts of moderately swift streams. The only other place where I have seen it is in Cuc Phuong National Park (in August), where I checked many streams, but only saw one female and one male in a small stream passing under the road in the middle of the park. Fresh individuals are bright green on the thorax and abdomen, but become brown and grey with aging.
