Real-life creepy bugs are one of my favorite science-related topics. Not sure why — maybe because it combines monsters and science.
Here’s the latest. First, we have book scorpions. I’ve only seen a scorpion in real life once. I was in El Paso and one of the suckers, pincers snapping away, was crawling up a bedroom wall. Totally freaked me out.
Well, it turns out not all scorpions are vicious. Not only are so-called book scorpions too tiny to harm us humans, they’re pretty helpful. These small creatures (there are over 3,000 different species) are only a couple of millimeters in length. What they love more than anything are booklice.
What are booklice? Bugs that eat the glue that binds books. And book scorpions devour these booklice. If it wasn’t for them, all our books would fall apart.
No word on whether book scorpions would help keep your Kindle clean.
The second of today’s tiny monsters is the Demodex mite.
This microscopic critter is a relative of spiders and ticks. And you are very familiar with it. How familiar? Right now there are scores crawling all over your body.
No worries, though. The mites that live among us are relatively harmless, though when their numbers get out of whack they can cause skin conditions such as rosacea.
It turns out that Demodex has been with us for a long, long time, perhaps as long as when humans first left Africa and spread out all over the world. Not only Demodex — there are several species of mites that scientists are just beginning to identify.
