Finally something in return!!

Dear WTB,
I have been following for a while and we have used it to identify a few interesting insects.  Being a biologist, Ichthyologist, I love biology. Most of the bugs I find, I know already, but I have something in interest for you.  Today, 25 June 2011, I just found our first Pseudoscorpion in Wellington, Colorado, USA.
I have a lot of macro photos, digital in JPEG format that I would like to share with you.  Some of the photos have a scale (mm) and some with UV blacklight (personal interest in trying to find scorpions) trying to see if they glow like scorpions.
Please email me and I’ll return with about 10 to 12 pics of closeups of the pseudoscorpion.
Thanks for all the work you do and I love the bug carnage as well as the identification.
You will also notice a red scale across the bottom of some of the pictures.  This is a ruler and the increments are millimeters.  This little guy was approximately 7 to 8 mm in lenth.
Enjoy and if there are any bugs in my area that are of interest for photography, please let me know.

Pseudoscorpion

Hi Sean,
Thanks so much for sending your photos.  It is interesting to learn that Pseudoscorpions do not glow under UV light the same way that regular Scorpions glow.  Phenomena like glowing under ultraviolet light might be evidence that certain creatures are able to “see” under different conditions, though this is purely conjecture.  Pseudoscorpions are harmless predators that are frequently mistaken for ticks by many people.

I have only found a couple of these bugs in my house but there may be a lot more that I am not noticing due to their tiny size. What is it? Is it harmful to my house or anything? Thank you.

Dear Chris,
We absolutely love your photo of a Pseudoscorpion.  It is a beneficial predator that will not harm you or your home.  It has no venom.

I found this bug when I was getting some old egg dying stuff out it is April in the Spring time. I sat the carboard box on the table and it came crawling out. I put it in a baggie and was trying to find out what it is…no luck. I do hope you guys can help me.

Hello,
I am glad to see I recieved an email back so quickly to at least inform me you have noticed I submitted my bug. I do thank you but I actually finally got the research I was looking for and found out what it was. So, please do not feel the need to have to research and send me information. Thank you again for your time and for the great website. It is very interesting to look through it all.
Have a Great Day!

Dear Miss Rebecca,
People don’t usually respond so politely to our automated response.  This is a harmless Pseudoscorpion.  It is a fierce, though tiny predator.  We hope your eggs turned out pretty.

Pseudoscorpion

Hi Josh,
The harmless Pseudoscorpion if often found in the home where it will prey upon small insects and other arthropods.  Since the Pseudoscorpion lacks venom, it is perfectly harmless and you have no cause for alarm.

Pseudoscorpion

Dear Brian,
The Pseudoscorpion got its name because it looks like a Scorpion, but it is not a Scorpion.  It has no stinger nor does it have venom.  You are correct that it is harmless.  Pseudoscorpions are able to capture large prey with those animatronic-like pedipalps.  Pseudoscorpions are also capable of phoresy, an activity by which they hitch rides of off other creatures, often flying creatures.  We have numerous images in our archives of Pseudoscorpions engaging in phoresy.

Spider, Tick, Tailless Scorpion, or something else???

I have found a bug in my home that I very rarely find and dont know what it is??? Today is the 3rd time I have seen this species since I lived here since 1994. I have found this bug mostly in dark places like the floor of our broom closet, and once fell off a box of spaghetti and onto my stovetop. This time however I was making our bed and say him and got excited while my wife was disgusted with a bug in our bed. I found a small zip lock bag and a piece of paper and scooted him into the bag. His attitude towards this was defensive and he always turned in the direction of the edge of paper and he reminded me of a scorpion, but without a tail. I found my wifes digital camcorder and went to go back to the ziplock bag to get a snapshot and the ziplock bag had a broken seam on the side so he escaped =( I would really like to know what type of bug he is and if he is harmless or not. When observing these guys in their habitat they are usually forraging in dust and using their s corpion like pinchers to bring stuff to their small mouth. So I dont know if mites have pinchers if this is what he is. Really bummed that he got loose. i have a stereo microscope and was hoping to get a nice picture of him. If I went to try to find them, i can never find them. I only find them by accident, so I am thinking their population within my home is very small. I drew a picture of what i found and can supply more info if needed. Added a dime to photo to give scale or the bugs size in lower left. Larger picture i drew to show pinchers and body features. He also has 8 legs + the 2 pinchers i believe.
