Could be a pseudoscorpion

I have seen this insect, too and I think it bit me!  This is going to sound weird, but, I had just gotten up from the toilet, and I saw one of these "ants with pincers" floating in the water.  I thought nothing of it and flushed it down.  Well, the next day, I had what I thought was a mosquito bite on the back of my thigh.  The bite is now about 6 inches long by 2 inches wide and warm to the touch.  It does not itch.  I am pretty convinced now that this thing must have been on the toilet seat when I sat down, nad then falleninto the water when I got up.  Of course, I didn't think to take a picture of the bug, but this was not the first time I saw one either.

I believe from your description that what you are seeing is a pseudoscorpian (do a google search).  They are harmless and actually quite beneficial.  Check them out here:

We have seen the same bug. My daughter took a picture of several of them at her friend's house. I can send you a copy if you tell me where I can send it to! I would like to know what it is!

I believe what you have are pseudoscorpions.  I found a smaller species in an oak tree at work today and was curious myself.  Turns our that you shouldn't worry about them.  They eat other insects and may actually be nice to have in you house.

I have one of these in a tiny bag.  I've found them before here in Maine.  I just told my son that this is a Maine bug because it has 'lobster claws'.  If you want the sample, let me know.

Check out this link to mites, I think this is more what you are talking about because the body is more oval, thinner not round and its tail (the end of the bug its not really a tail) looks like a snakes tongue it seperates like a v.

Yeah, i don't know what it is but I have just got the same bug in a jar beside me now and am trying to find out myself. I hope you find something out soon because these things are starting to scare me.

From your description it sounds like a lynx spider. Pretty much looks like a stripeless wolf spider with small black pincers that almost resemble boxing gloves. Their venom is relatively harmless to humans.

Is this the what you are talking about? No idea what it is.

That one just linked above is what I keep finding on my ceilings. I have no idea what it is / if it's at all harmful, but it looks just like the picture that CD posted. Any idea what that could be?

I also Have these creatures In my house i actually saw one today in the sink. My camera wont take a picture of it clearly since it is a very tiny insect. But I think they look like little tiny crabs. They have a head and a body with 2 little pincers coming out the front. I have seen these before in a house i grew up in when i was a young girl but didn't think anything of it. Now I see them and am not sure what to think... Are they Harmful or harmless? Not sure since No one seems to know what they are. I live in West Central Minnesota too by the way if that help any.

I am after finding two bugs which sound like these! Extremely tiny spider or beetle with long antenna like things coming from it's front. The ends of the antenna have what lookto be minature lobster claws or something of that nature. I have never seen this before and have now found two in our washroom in the past week :s

I have a picture very much like the description given here of a bug we can't identify!

I was mushroom picking today and this little guy came in the house in my basket:approx 3mm long,1mm wide,glossy beetle-like black body larger and rounder in back than streamlined front half.4 very slender brown legs each side.can walk forward or backward.coming from his front center are two 'arms' each approx 3mm long with a pincher at end of each.when he's walking,the  'arms' extend from his body at approx 45' angles then bend -like at an elbow-sharply forward in defensive / offensive mode. I guess they look like what a scorpion wings,no jumping,no web building,no antennae.western washington state
