Description
It is a medium sized damselfly with velvet-black head, thorax and black-capped brown eyes. The dorsum of the thorax has narrow citron-yellow ante humeral stripes in the sub-adult and teneral stage. The sides are citron-yellow, marked with a broad oblique black stripe over the postero-lateral suture in that stage. But all these marks are obscured by pruinescence in adults. Abdomen is black, unmarked in the adult; but with narrow bluish basal rings on segments 3 to 6. There are yellow marks on the lateral sides of segment 1 and 2 in sub-adults. Female is similar to the sub-adult male with yellow marks. It breeds in ponds and marshes in forests.
