I don't know. Ours were emerging afterthe warm weather started, so that was some time in June. I suspect weather has something to do with it - maybe they don't emerge until the water has warmed up for example. And they come out on sunny mornings, not overcast or rainy days.

I'm amazed any survive in the old pond here because it's teeming with

time? May/June?
