Dear c_seiber,
This is a harmless Pseudoscorpion.  Various species are found nearly worldwide, and they are often encountered in peoples homes where they do their best to dispatch unwanted insect and arthropod visitors.

I found this bug twice in our bathroom and this morning in our kitchen. I was reading the paper and it might have crawled off my t shirt. Unable to identify it.

Dear Doug,
This is a harmless Pseudoscorpion, a minute predator often found indoors. We get countless identification requests from around the world on Pseudoscorpions, and we should probably include it in the Top Ten Tag. Though your photo is not the most detailed we have ever received, we love the inclusion of the ruler in the photo so our readership can see just how tiny this amazing predators really are.

cerambycid with pseudoscorpion attached
Hey Bugman!
Thought I’d send a couple of pics I think are interesting. I took some photos of what I think is a species of cerambycid that has a pseudoscorpion attached to it. Thought you might want to see them. Oh, and I always forget to add this, I took these in Fort Gordon, Georgia about 2 weeks ago.

hi Stefan,
We wish we could tell you exactly what species of Wood Boring Cerambycid you have in your photo. We will seek the assistance of Eric Eaton. We can tell you that the Pseudoscorpion is hitching a ride with the flying Cerambycid, a technique known as Phoresy.

Update: (06/12/2008)
Hi, Daniel:
Welcome back! Coincidentally, I just visited the site today, after ignoring it while you were away. LOL! Hope you had fun in Ohio. I miss the lush vegetation out there…. The cerambycid is probably the “spined oak borer,” Elaphidion mucronatum, named for the pair of spines at the tip of each wing cover. Cerambycids in general seem to be favorite modes of transport for pseudoscorpions.

Confirmation: With Different Common Name(6/12/2008)
Hello Daniel
The long horn in question looks like the “Spined Bark Borer” Elaphidion mucronatum due to the long femoral spines which sorts it out from Parelaphidion spp. and a longer spine on the 3rd antennal segment. Hard to tell for sure due to angle of the photo. Seems to be to robust to be an Anelaphus spp. I hope this helps. Keep up the good work as always.

Tiny Crab Like Bug
I was sitting at my computer when i noticed this little thing crawling across my desk. It has long crab like pinchers, and 6 little legs, teardrop shaped body that was extremely flat with stripes brown in color. Sorry my first instinct was eww bug kill it. I did take a picture after its death. Its next to one of my hairs to show relation to size. What is it? Do I need to worry? Thank You

Hi Matthew,
We are so busy right now that we can only answer and post a small fraction of the numerous letters we are sent. Were it not for your very descriptive letter with good search terms including crab-like and your wonder image with the open claws on your Pseudoscorpion, it might have gone unanswered. Pseudoscorpions are quite harmless, but they are fierce predators if the prey is small enough for them to capture. They are known to catch and eat house flies much larger than themselves. We also hope the next Pseudoscorpion that crosses you path will continue unharmed as this is truly unnecessary carnage.

what is this?
Found this on my windowsill in my kitchen in Georgia. What is it? I thought perhaps it was a baby scorpion?? For an idea of size, one of the "arms" is between 1/8" and 1/4". Any idea? Please reply!
Amy

Hi Amy,
The Harmless Pseudoscorpion is one of our most common identification requests.
