Ascalaphs are these 3 foot long furry antlions. Like their smaller (less than 1 inch) earth counterparts, they dig deep pits and lay in wait with their sickle shaped jaws at the bottom, ready to clamp onto their prey and suck em dry. Fields of them are used like a mine field to protect remote farmlands.
Their jaws are bright red. They will help each other by flinging sand when they sense vibrations, hoping to knock the victim into a pit. They have poor eyesight and cue in on vibrations.
