I was out last night above the river to take some pictures, and I noticed that as the sun went behind the mountains I was joined by some unwelcome visitors: mosquitoes.
I suspect they were males as I didn't end up with any bites, and they were mostly hovering above me. A few landed so I squished them. I don't know what kind they were other than "generic mosquito." I was in the same area last week and didn't encounter any, so I think it's just starting.
All this to say, it's probably worth thinking about taking typical mosquito precautions when recreating outdoors in the evening away from town. Here is some information about mosquitoes from UC IPM.
