ootheca hatching

I was able to catch one of my mantid ootheca hatching - it was so cool! They don't leave any holes to speak of and now I know why!! :eek::eek: I'll put the You Tube link on here - hopefully that works for people. The video is only a few minutes long, but it's taking me forever to upload...
