Attracted by the lights in the store, a swarm of Scorpion-Flies land on the store windows at night, apparently attracting a flock of Pterobuzzards in the process, which pluck and devour the Scorpion-Flies from the store windows, eventually breaking one of the windows open.
FilmEditFive Scorpion-Flies escape into the store through the broken window, one of them managing to sting Sally. Two are crushed or cut to death by Tom and Amanda, while the other three are eaten by a Pterobuzzard.
At the end of the film, what appears to be a Scorpion-Fly hive is seen attached to a tree. When a military convoy passes by the area and the mist dissipates, a soldier incinerates the hive with a flamethrower.
NovellaEditThe Scorpion-Flies are described as plump, segmented creatures with a stinger/sex organ, burnt-colored flesh and eyes on stalks protruding from their heads.
The Scorpion-Flies in the film don't have eyestalks, have hard, purple, segmented shells and resemble a cross between a wasp and a scorpion. Their stingers also contain a neurotoxin which causes massive swelling and suffocation in minutes.
