The small-but-mighty beaded lacewing larva wields silent-but-deadly flatulence to turn the tables on would-be predators.
"When a larva comes across some termites, it raises its rear-end to the termite's head-height and releases a vapor-phase toxicant called an allomone which knocks them out, and the larva feasts on their frozen bodies. In essence, it farts them to death. Depending on how many unfortunate termites are downwind when the toxic toot fires off, a study found that the larva can actually take down multiple termites with a single poof."via IFL Science
