JW, with all your rain and standing water, I'm surprised you have not seen them if they are there. When I was walking in the mud yesterday, I saw tons of tiny black specks "walking on water", and wondered what they were. They swarm, never saw just a couple, always a bunch. So, go outside, walk around in the ditches of water, see if you see any! I didn't notice any on my pond, just out in the pasture in the little holes from the horse and cow hooves, where water was standing. I was also using the hoe to trench the water way from where the sump pump from the house exits, saw a bunch of them there, too. Funny, that I saw them on the same day Zen posted this! I love seeing questions solved on this forum.
