Google 'ant lion'

THAT'S IT!!! Wow, so those are sand traps. Kind of cool! Other then
a potential biting risk sounds like these guys eat ants so maybe it's
a good thing to keep 'em around :O)

As a kind we called them doodlebugs. Tickle the bottom of the mound
or place a small amount of sand in the mound and you will see the bug
begin to clean the mound out. If you lightly blow into the mound, you
might get to see the bug.
