Close. They are considered remarkable because of their ability to shoot a boiling, corrosive substance at predators. This False Bombardier Beetle (Galerita janus) (probably) has dialed it back just a bit. They seem like needless pests but they’re actually really important to our ecosystem. 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. Some, like this false bombardier beetle (Galerita sp. Virginia, USA. But—the BugLady promises that it does not contain elves, reindeer, Grinches, chipmunks, snowmen, or Jimmy Stewart.
