in boggy places, particularly at the mouth of small tributaries. We found it 
about ponds and puddles in the Godbout River flats, which were refilled at each 
tide and were therefore ecologically different from stagnant ponds. 
Adult life probably begins in June throughout the greater part of its range, 
probably July in Labrador. 
With the exception of a male—I have never seen this species away from the 
immediate vicinity of water, nor have I ever observed it hawking at any great 
height. The males fly in sunshine within a foot or so of the water, patrolling 
small areas in the usual way. The female oviposits by tapping the surface of the 
water with the abdomen.
