Bug

An earthquake releases a bunch of mutant cockroaches that can create fire by rubbing their cerci together. Eventually, most of the bugs die because they cannot survive in the low air pressure on the Earth's surface, but a scientist, Professor James Parmiter (Dillman), keeps one alive in a pressure chamber. He successfully breeds the mutant cockroach with a modern cockroach, creating a breed of intelligent, flying super-cockroaches.
