I remember taking the photo but can't remember what we were looking at! We did see a few baby Preying Mantis...maybe that's what it is?
This is Balsam Gourd, Ibervillea Lindheimeri (Lindheimer's Globeberry) I'd never seen it before so I had to check out it's uses and found that the seeds are eaten by scaled quail and the leaves, in a drought by white tailed deer. It is unique to the Edwards Plateau.
We had a great time at the ANSC and if you're looking for something new and educational to do with the kids head on out there...it's fun for the whole group! Those of you interested in the Master Naturalist program, watch out for the applications to show up online sometime in August. Get it in early, I was on the waiting list for two years!
