On Coyote Creek, a warm sluggish stream with mud banks and much mud 
bottom, it does not appear about the water in numbers until about 11 in the fore- 
noon. EHarlier than this it can be found on the sunny patches of bare ground back 
a few yards from the creek bank. It is active about the water during<thetheat 
of the day but leaves about four in the afternoon. The males are four or five times 
as abundant as the females, and usually stay low over the water, seldom rising

higher than four or five feet above its surface. They usually rest on the bare 
sandy spots but alight also on logs, brush and willows. The females oviposit by 
tapping the surface of the water with the abdomen at irregular intervals as they 
fly close over its surface. It is at such times that the males swoop on them and 
take them away in copulatory flights, which end in a long resting period in 
copulation on some tree or bush.
