Southern black widow babies

I've seen a lot of adults, mostly females, on the outside of our building, and a good share of egg sac, but this was the first time I got to see the kids. I took one of my classes out to see them a couple of days after I took the pics, but they were all gone. I don't know if they were killed, eaten, or found crevices to take up housekeeping in.

Beautiful series of all the babies! :)
