Forcep, thank you!!! I just looked them up on Google and it looks like the common name might be Ebony Bug.
Attached is a picture I found on a site that called them a type of Guyana True Bug. I wonder what they are good for? Maybe the little blue tailed lizards around here eat them...
You are both right! Family: Thyreocoridae Species: Cydnoides renormatus. This forum is so awesome. Thank you!
So I think it isn't the Ebony Bug then because it looks exactly like the picture of Cydnoides renormatus that I found on the web.
Amazing what you can find in the backyard when you stop to look Doesn't seem to be much info on the web about them - at least info that non-entomologist-type-people like me can understand.
