Subject: Bug that crawled out of Madrone wood
Location: Woodside, California

We gave a friend some Madrone firewood in November 2012 from a Madrone that fell on our property approximately 5 years ago. She sent us the attached picture of some bugs that crawled out of the wood. We’d like to know what these are. Our location is a wooded property in Northern California bordering on open space, Santa Cruz mountain range, mainly redwoods, some oaks, bay and madrone.

Pseudoscorpions

Hi Hans,
These are harmless Pseudoscorpions.  Typically, we get photos of Pseudoscorpions from people who find them in the home and we allay their fears by telling them that they are harmless predators that feed on many undesirable household intruders.  If this pair of Pseudoscorpions crawled out of the wood, they were most likely hiding under the bark or in cracks.

Thank you so much Daniel for identifying these bugs.
I am happy to learn that they are not only harmless but
useful as well.
Have a nice day
Hans

Hey! did a google search and you guys came up. Found a couple of these guys in our bed the other day, was under the impression bed bugs were very small. Doesn’t seem like a flea either. i have know idea. There about as big as a small woodtick, about a quarter as big as your pinky nail. Very flat. We saw about 6 of them. Any help would be awesome, thanks!

Pseudoscorpion

Hi Trevor,
This is a harmless Pseudoscorpion, and since they are predators, they will feed upon Bed Bugs.  We would urge you to tolerate their presence and hopefully they will keep your bed and home free of unwanted pests.

Pseudoscorpion

Dear Shower Psycho,
You have discovered a Pseudoscorpion, a harmless arachnid that has no venom unlike its stinging namesake.  Pseudoscorpions are cosmopolitan in distribution and they are rarely noticed because of their tiny size.  They use their claws to capture prey, and they are beneficial predators.  They can also use their claws to attach themselves to larger flying insects that they use to transport them to new feeding grounds, a phenomenon known as phoresy.  Since it is the end of the month, we need to select a Bug of the Month for May, and we are choosing your submission.

Small insect on antennae
Location: Wellington, New Zealand
March 16, 2012 7:59 pm
Hiya, I’ve got this photo of a weta and it was only after downloading it from my camera that I noticed there was a tiny little insect attached to the weta’s antennae. Can you tell me what it is? It’s got claws like a crab or scorpion. This was taken in Karori, Wellington, NZ in my front garden. Lots of stones and trees.

Phoresy: Pseudoscorpion hitches ride on Weta!!!

Dear Angela,
You have taken a marvelous photograph.  First we must say that we love your New Zealand Wetas.  They are amazing insects.  The hitchhiker is a harmless Pseudoscorpion.  The act of using another creature for transportation purposes is known as phoresy, and we have several interesting images of Pseudoscorpions engaging in phoresy on our website, including a House Fly, an Ichneumon, a Cranefly and a Longicorn.  Thank you again for your wonderful photograph.

Pseudoscorpion Holding onto House Fly
Location: Southwest Indiana

Hi!
I just want to let you know how much my family and I appreciate your site. After searching, I never fail to identify the bug I am looking for.
I am including pictures of what I believe, thanks to your site, is a Pseudoscorpion hitching a ride on a house fly. He was actually holding onto the fly’s mouthpiece, much to the fly’s dismay. The fly would constantly stop and try to pull the little guy off.
Afterwards, we released the fly and his hitchhiker out in the garden. Thanks again.

Phoresy: Pseudoscorpion and House Fly

Hi Heather,
Thanks for the compliment.  This phenomenon of hitchhiking is called Phoresy and Pseudoscorpions are quite good at it.

Bug ID
Location: North Eastern Illinois
July 22, 2011 6:10 pm
This little guy (or girl) was found in a home in a wooded area of North-Eastern Illinois (Lake County). He (or she) is only big enough to sit on your pinky nail, and has a plump, elongated and segmented abdomen, apparently six legs not including two dispropotionately large front pincers. There appear to be two antenae protruding from the head, but those may be an additional set of legs. Coloration is black or deep brown, yellow or white striping at the segment seams, and on the belly. The pincers and legs appear to be red-ish.
Hope you can work with that and the picture!

Pseudoscorpion

Dear K-Dizzle,
This is a harmless predatory Pseudoscorpion.  It will not harm your or your pets (unless your pets are small insects) and it will not damage your home.
