Texas Bugs Everywhere

I got home from vacation recently and found my yard in the Texas hill country swarming with these black bugs. I have never seen anything like them and I am curious what they are.
Plus, I have a little kid in the house who likes putting things that move into his mouth, so I am wondering if they are in any way poisonous.
This is the larva of a Caterpillar Hunter in the genus Calosoma, and though we cannot identify the exact species, there is a good chance it is the larva of the Fiery Searcher, Calosoma scrutator. Interestingly, we just finished posting a photo of a Fiery Searcher. Both the larva and the adult Caterpillar Hunter is a fierce predator that can consume large quantities of caterpillars. They are not poisonous, but they might bite if carelessly handled. Though it may hurt a youngster, the bite of a Caterpillar is not dangerous.
