Looks like the same species in this shot.

Moved from Proctacanthus.

Proctacanthus
Definitely the right genus. And they are known for ovipositing in sandy soil and dipping half the abdomen in the sand to do it. Unfortunately Florida is rich in this genus. However, P. fulviventris is known for having a bright yellow facial hair coloration and has femurs and tibias contrasting with one black and the other red. That species is a GA FL specialty so I have never seen it. I am betting fair money that this is it.

 
Thanks Herschel!
...you can see the markings on the legs in the other shot more clearly...here they are a bit dark overall, but there is still a reddish hue to the lower leg...

This is the female fulviventris. See the other shots that I am now working on sorting.
