I live in New Mexico. My yard is all rock with no grass at all. I have two trees in my yard they only like one of the trees. The bark is about to turn red from the amount of them. They're crawling on the rocks every morning and they're not mites as I already looked that up. They also have partners that are just a little bigger that look like sunflower seeds with legs and they fly too. The red bugs are small, maybe 4 millimeters in length, and they all seem to disappear as the sun come up.
