Each has blue elytra (wing coverings) and a reddish head and limbs. True to its name, this beetle greatly resembles a family of beetles that can fire pulses of hot chemicals at perceived threats (including humans). They seem like needless pests but they’re actually really important to our ecosystem. Bombardier beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—which are most notable for the defense mechanism that gives them their name: when disturbed, they eject a hot noxious chemical spray from the tip of the abdomen with a popping sound. They have wings which make them good flyers. The bombardier beetle is inspiring designers of engines, drug-delivery devices and fire extinguishers to improve spray technologies. Thanks to the reputation of its dangerous look-a-like, the False Bombardier Beetle may be less preyed upon. Description: 3/4 - 1 inch long. According to bugguide.net, Galerita comes from the Latin galeritus, meaning wearing a fur hat. I wish to thank Vassili Belov, Blaine Mathison, and Drs.

Its spray consists mainly (80%) of concentrated formic acid (which is also deployed by ants), with some acetic acid and wetting agents thrown in. Many of the more talented members of the family are able to produce noxious chemicals to spray on their enemies. False Bombardier Beetle. General Characteristics. They are considered remarkable because of their ability to shoot a boiling, corrosive substance at predators. 8 spp. The easiest way to separate False Bombardier Beetles from "real" Bombardier Beetles is that the False Bombardier Beetles have a dark head.

This halloween-colored insect is a False Bombardier Beetle ( Galerita bicolor ), there are two similar species within this genus, the other is G. janus and the only real way to tell them apart is the shape of the head and pronotum (thorax area). The larger chamber contains hydroquinones and hydrogen peroxide (HQs and HP), and the smaller or reactor chamber holds oxidative enzymes (OE). Posted by 5 months ago. The African bombardier beetle, Stenaptinus insignis, has been extensively studied to understand its remarkable defense system.

Long antennae have thick orange segments coming off the head. Its spray consists mainly (80%) of concentrated formic acid (which is also deployed by ants), with some acetic acid and wetting agents thrown in. Its spray consists mainly of concentrated formic acid, with some acetic acid and wetting agents thrown in. A hot chemical spray causes the predator to vomit. The beetle… More information on False bombardier beetles A pretty good trick for a cold-blooded critter. This beautiful False Bombardier Beetle is about twice the size of the “real” Bombardier Beetle. Bombardier beetles have the morphology of image F (Kanehisa & Murase 1977). They meander along rocks, logs and leaf litter, and may be active at night as well as during the daytime. Their elytra (the two hardened front wings that provide protection for the flying wings folded beneath) are often shiny and pitted or grooved. Galerita spp. Genus. An important trait of Galerita bicolor is a red spot on top of the head, best seen in the third photo on this page. The researchers used high-speed synchrotron X-ray imaging to watch what happened inside living bombardier beetles. Their explosive defence mechanism can kill other insects and scare off larger predators. Waldbauer, in his The Handy Bug Answer Book, claims that drop for drop, the chemical is more potent than skunk spray, and says that a toad that is sprayed in the mouth gags, sticks out its tongue and rubs it against the ground. According to Eaton and Kaufman in their Field Guide to Insects of North America, the Bombardier beetle can squirt nasty stuff, which discourages some predators and can stain people’s skin, in rapid-fire bursts or pulses (it’s the only insect known to have a pulse-jet) accompanied (like fireworks) by an audible “pop” and a visual “puff.” As a bonus the stuff has a temperature of 100 degrees! They are also known as Slender Ground Beetles. Comparative anatomy of carabid pygidial glands. Chronological Index to the Field Station Bulletin. Most were a big surprise to homeowners; some were typical “house bugs,” but many were outside bugs that wandered in; and true “pest species” were rare. This volatile load is not carried around “as is”, it is assembled on demand. Both Greek variations denote "shortness", a reference to the the beetle's shortened elytra.

So, beetles have developed predator deterrents, and “most often these defenses take the form of dischargeable glands, present in the abdomen, and opening on or near the abdominal tip.” Such glands are a standard feature in a number of beetle families, including the Carabidae, Dytiscidae, and Gyrinidae [the ground beetles, predaceous water beetles, and whirligig beetles]. False bombardier beetle (Galerita bicolor). in our area (all but G. aequinoctialis in the subg. ), probably just wander in … This explosive spray can reach temperatures close to 100˚c! The hot spray from a large Bombardier Beetle is also painful to humans. 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 elytra have linear ridges. The African bombardier beetle, Stenaptinus insignis, has been extensively studied to understand its remarkable defense system. They are generally flattened insects with obvious mandibles (jaws). Formic acid smells bad and is noxious to vertebrate and invertebrate pursuers alike. Both inorganic and organic chemistry were a mystery to the BugLady, but not, apparently, to the Bombardier beetle. 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 pygidial glands of Bombardier beetles are different to those of other carabid glands in that they have two chambers: the much larger reservoir and the smaller reaction chamber (Eisner, Eisner & Siegler 2005). The black abdomen is covered by elytra that have ridges running the full length. Brachinus is derived from classical Greek βρᾰχύνω [ῡ] = brachyno or βρᾰχύς = brachys with the accent on long upsilon.

Its mimicry of the colors and shape of a bombardier beetle help it evade predators. The false bombardier beetle is common across much of North America, but it is most commonly sighted in moist, wooded areas and backyards. Trade Secret #1 is that insects, being both cold-blooded and quick, are slowed down a bit by a brief sojourn in the refrigerator (a longer stay, alas, accidentally kills them). Folks sometimes ask the BugLady how she gets some of her photos. Galerita aequinoctialis. The False Bombardier Beetle is described more by what it cannot do than by what it can. Like other media in the period between Christmas and New Year’s, this is a rerun, though it is slightly enhanced from its original appearance eight years ago. Some, like this false bombardier beetle (Galerita sp. This False Bombardier Beetle (Galerita janus) (probably) has dialed it back just a bit. 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. More than 40 species of bombardier beetles are found in the United States. This False Bombardier Beetle (Galerita janus) (probably) has dialed it back just a bit.
