Brazos Bend SP

An, Herper Bob & I met up with Dr. Hall's VNH class at Brazos Bend SP around 3:30 on 5/21/06. After setting up camp, the class went on a hike, after that it was dinner and then night driving for herps. An and I went with Amy's van for night driving. Students in the van asked me hard questions such as if I was to choose between a girlfriend or my collection of snakes. What would I choose?  The latter, of course! Thats like asking Jane Goodall, to choose between studying Chimps or getting married.

Spider Wasps (Family Pompilidae)

Even though we are a Vertebrate Ccass, we still stop to look at cool Inverts. This female Spider Wasp has stung and paralyzed this spider. She is now in the process of dragging it into a burrow and laying eggs on the spider. Adults feed on nectar.
