The Fainting Bug! Enoclerus sphegeus
I like beetles. There are interesting ones all over the place…and they do REALLY interesting things. Some can cry like babies. Some like to pat poo into nice little balls and roll them back to their home. Some hang around to take care of their offspring and even “play music” to call them to breakfast…or lunch…or dinner! Some do “bad” things like eat your plants …or your trees…or your house! Some wear really cool suits of shiny armor. They can look like miniature versions of dinosaurs or imaginary space aliens! Some have really cool names…like this one I found the other day…with many friends…hanging out on a dead fir tree. Its name? The FAINTING beetle! That’s exactly what it did when I walked up….fainted right over onto the ground! Stayed that way too…for about 30 seconds with its bright red (aposmatically colored) abdomen warning me it would taste VERY bad if I decided to eat it. No worries there little bug. I was only going to take your photo. Now the scientific name of this fella (or maybe it was a “she”) is Enoclerus sphegeus. It eats the bark beetles that eat fir and pine trees. Check out the photos and next time you see a beetle, take a moment to “admire and inquire” before you automatically stomp it! Not all bugs are bad.
