I didn't have time to check my "farm" this morning before we left for the day. When I got home in the evening, I found a few new pupae and forty-six new beetles!! I've posted a picture of them before I added them to their friends.
I've found that the best way to pick up the beetles is to flip them on their backs and touch them with my finger. They'll just grab the tip of my finger with their feet and I can move them to the cup I use for transfer.
