Has anybody ever heard of these?

A lady on a nature walk yesterday showed us where ant lion larvae hide--in sandy inverted cones about the size of an inverted anthill.

You can take a little bitty piece of twig--or a pine needle!--and stick it down into the cone and the little ant lion will bite the end of it if you can find it.

These larvae feed off of ants that crawl--unsuspectingly--down into what the ant thought was an ill-constructed anthill. [Yes, my imagination is taking some liberty here.]

That little ant lion is really a little angry lion temperamentally: it quickly chomps on that ant and eats it up.

I'm going a-googling to see what these little creatures look like once they're fully developed.
