A fiery orgy may sound like an awful idea, but for these bugs it comes with a number of advantages… These insects, which are roughly the size of pumpkin seeds, are pyrophilous — meaning, they love fire. They actually depend on it for their reproduction. When most animals are fleeing from wildfires, these insects fly toward the flames, copulate among the embers, and lay eggs. Those eggs then hatch into wormlike larvae that feast on the recently burned wood… Sensors in their antennae — known as sensory pit organs — detect infrared radiation, which is a proxy for heat. Located on the insects’ underside, those pits point them in the direction of a fire. These beetles may also be able to detect smoke.
