I have them too! Some on Christmas trees, some on the bottom. None on the sumac tree I sunk. Looks like fine brances it is!
The cool part is I caught some of the action this evening. I saw the large individual females being followed by a swarm of smaller males in several places. I did not witness the actual egg laying though, but they seemed oblivious to my presence.
It turns out I have a ton of perch, and the BCP are barely making an appearance.
