I got to the swarm this morning: here are some pics:

I opened the roof and saw that the swarm didn't reach that high, so I filpped back the top super.

Here the main body of the swarm is exposed.

In the process of reorganizing the frames, I spotted the queen---looks like she's young and mated.
Initially I had some doubts about her having been mated but the way she carried herself, slowly and carefully, it was obvious that she wasn't a virgin.

If you look toward the bottom left of this sheet of foundation, you can see how much wax the swarm put on it (look for the lighter color of the new wax and the deeper cells relative to the imprinting on the foundation).
Bottom line---the swarm was a nice one, not small, but not a really big one either. I decided to keep it as it was and to build it up ---- until I found that one of the two earlier swarms I got this spring was queenless and had laying workers. Before this swarm gets settled down in its' present position, I intend to move it (tonight) to the site of the queenless swarm, place it on the stand and put the queenless on top. Tomorrow I hope to shake the bees off all the frames of the upper, queenless hive and have them merge by coming "home" to the swarm.
All comments and criticism welcome.
