The easiest way to separate False Bombardier Beetles from "real" Bombardier Beetles is that the False Bombardier Beetles have a dark head. When attacked by predators, mostly ants, the beetle unleashes bursts of its hot chemical spray accompanied by audible detonations.

About 1/8 - 1/2 inches long (a few can become as large as 1 inch in length). When threatened, the Bombardier beetle presumably squeezes some HQ’s and HP into the OE in the reactor chamber, where the chemicals mix and produce a thermodynamic reaction—smoke, mirrors, liquid and heat—that can be precisely aimed.

The late Thomas Eisner, entomologist extraordinaire, explained that while elytra help beetles by protecting the flying wings from damage, they potentially put beetles in harm’s way because the flying wings are not “flight-ready”—in order to fly, the beetle must first unfold the membranous hind set of wings from under the rigid front set, and that takes time. Living In Warmer Humid Conditions These Burrow In Dirt, Loose Tree Bark And Forest Litter. Scientists who experimented on the False Bombardier Beetle by pinching various legs and antennae report that the beetles spray accurately toward the side and the appendage that is being pinched, and that a left-side pinch activates only the left-side apparatus, and vice versa. The very flexible trailing end of its abdomen houses, along with the usual insect paraphernalia, two large glands (one left, one right), each with its own “exhaust pipe.” Each gland is divided into two sequential chambers separated by a valve.

Galerita aequinoctialis. Paired abdominal glands are also standard equipment in the False Bombardier Beetle, but they only consist of a storage chamber and a delivery chamber that is surrounded by compressor muscles.
