False Bombardier Beetles are a member of the Ground Beetle family, which is large and diverse. But—the BugLady promises that it does not contain elves, reindeer, Grinches, chipmunks, snowmen, or Jimmy Stewart. Formic acid smells bad and is noxious to vertebrate and invertebrate pursuers alike. 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). Her mashed potato serving bowl made a perfect backdrop for this beetle. False Bombardier Beetle This False Bombardier Beetle (Galerita janus) (probably) has dialed it back just a bit. 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.Folks sometimes ask the BugLady how she gets some of her photos.

Formic acid smells bad and is noxious to vertebrate and invertebrate pursuers alike. They can still spray repulsive chemicals, so not sure where the “false” applies! My first encounter was a few days ago, I woke up in the middle of the night to one of these crawling up my neck into my hair(literal worst nightmare). They meander along rocks, logs and leaf litter, and may be active at night as well as during the daytime. Located in south central Iowa.I find at least one False Bombardier Beetle in the house a day. You may read more about it on BugGuide, including the warning that “Caution: These beetles have chemical defenses (see Rossini et al. Is it the same bug or different but related? Come to lights, sometimes wander into houses.” 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. 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. You will receive a new password via e-mail. Its spray consists mainly (80%) of concentrated formic acid (which is also deployed by ants), with some acetic acid and wetting agents thrown in. Then there was one just wondering around in my bathroom, then another today. Thanks again so much!I found one false bombardier inside my house one evening. To the people who laugh at the BugLady’s album of indoor bugs, she has this to say: Researchers studied 50 homes in Raleigh NC, cataloging every arthropod they saw.

Hi Michael, This is a False Bombardier Beetle, probably Galerita bicolor. Their The Brachinus Bombardier beetle, not pictured here, is a chemical marvel. You can compare your image to photos on BugGuide. According to Eaton and Kaufman in their This volatile load is not carried around “as is”, it is assembled on demand. Do they normally bother humans this much!

This False Bombardier Beetle (Galerita janus) (probably) has dialed it back just a bit. The larger chamber contains hydroquinones and hydrogen peroxide (HQs and HP), and the smaller or reactor chamber holds oxidative enzymes (OE). It’s found in open woods and brush piles (and the BugLady’s basement and bathtub), where it often preys on caterpillars (but not in the BugLady’s bathtub). 1997)”. Both inorganic and organic chemistry were a mystery to the BugLady, but not, apparently, to the Bombardier beetle. As unwanted visitors go, you could do much worse than this False Bombardier Beetle. Could that somehow be attracting them?Please enter your username or e-mail address. For years, the BugLady misidentified this leggy, inch-long beetle as a Bombardier beetle (genus Both are in the Ground beetle family Carabidae, a group of (mostly) dark-colored, speedy, long-lived, nocturnal carnivores.

They are hard to squash.I have several in my converted basement home in Kansas, but their legs are black. Waldbauer, in his This beautiful False Bombardier Beetle is about twice the size of the “real” Bombardier Beetle. This is a False Bombardier Beetle, Galerita janus.
