I wonder if it was a baby muskmare! Probably not, I bet they build an egg case like mantids. Need to find out. Otherwise, I've seen some gigantic black beetles, too. Good thing I decided to go to the store- there's a big thunderstorm brewing, and I can't find my drill bits for the 12" nails- how can you lose big things like that??? Oooh, I rescued a spider and egg case and put her in Fort Tort. You know, that's what's going to be so cool about having the turtles out there- they are so interactive with humans- they love their treats and think every time I peek in they are going to get treats! The torts vanish for months at a time- the boxies are always out, always alert.
So Jen, I'm making them a sort of pebble fountain, but with about a two inch deep water level. How deep would you make the reservoir? A foot? 18"? Two feet? I'm thinking 4x4. I'll run irrigation to it to help keep it topped off.
