“The drill-worm. Its butt can drill through wood, human flesh, bone, and just about anything else but glass, rock, or steel. Both of these bugs are bioluminescent and highly active, day or night. You don’t want to see either of them without something between you and it.” Andy, Pandemonium

Drill worms are aerial carnivores native to Hender's Island.

Drill worms have radial trisymmery. Each of their three sides has a wing on the top, a raptorial preying mantis claw in the center, and a leg on the bottom. The bottom ends in a drill.
