Doodletown

Beneath the house a moonscape of desperation and death awaits the unsuspecting...
Mmwwaahhhh.....

Nah, not really. There are just a bunch of antlion larvae hanging out, waiting for insects to fall into their little pitfall traps. A trap is shaped so that as an insect struggles to climb out, it instead slides in - the proverbial slippery slope ;) If it doesn't slide in fast enough, the "doodlebug" flings sand at it with its jaws.

If you look closely, in the center of the picture you will see the head and jaws of a larva. It is most likely in the genus Myrmeleon. Afraid I don't know the species...
