Desert stalker

s are creatures found in the American Southwest. They are giant, mutated antlions.

Characteristics
One of the lovely predators unique to the Sonoran desert and its outlying areas, the desert stalker attacks by burrowing up from the ground underneath the victim and biting him with razor sharp mandibles. Desert stalkers have an uncanny ability to go for the weakest person in any group. They will usually attack that person in spite of repeated attacks from others.

Appearances
s were to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios.
