I love those UF articles. Use them all the time. And the wording is very close to how I described the insect. I'm looking through the pictures and it looks like they only have two wings, but I see in the second link and the drawing on the UF article that they have hind wings, they're just much smaller. And maybe the hold them under the fore wings? I guess that's why it only looks like two wings?
Dad's a woodworker so we have lots of wood laying around, but he usually coats it with some kind of sealer (end seal, I think it's called?) and keeps it under a tarp. But I'll give him the heads up about the bees. I like them. We also have plenty of trees with dead limbs and such; I don't know if they would use those. I think all the houses on my street are concrete and stucco. The only wood I remember was the beams in the roof when we built the place (not counting interior stuff). So I can't imagine the bees would be a problem.
