Sounds like the mid Atlantic Maryland and northern Virginia area - Hot, humid, and no breezes :)
I find that the bug netting on most tents stops all breezes. In hot, humid climates - a tarp much cooler at night. I do get 1-2 spider bites and 3-5 mosquito bites each night (sleeping in my boxers with a 100 wt fleece for the wee hours) - but it's worth it for the extra 3-4 hours of sleep. Also, note that Mosquitos seem most active at dinner time, dusk, and an hour or two into the night. Since this is before bed time, most people assume the Mosquitos will bite them all night if they sleep under a tarp. Not so. Try it and see :)
However, my wife is afraid of snakes, raccoons, foxes, etc that are roaming around at night. (even though none have ever bothered me while I'm sleeping). So when we hike together, we use a tent with mosquito netting (NOT no-see-um netting) which allows a little bit of breeze through the mesh, and dual side doors that open from the top so the netting is only closed for the bottom 18". The open doors make a huge difference, and are about 1/2 as breezy as a tarp.
