Good eyes! That looks like a pseudoscorpion. As Wikipedia says: They are tiny and inoffensive, and are rarely seen due to their small size, despite being common in many environments. Pseudoscorpions often carry out phoresy, a form of commensalism in which one organism uses another for the purpose of transport.Beatsy wrote:In the first pic, there's a red thingy on top of the left eye that seems missing in the rest. Reminiscent of a mini scorpion (but obviously not). Any ideas?
I had never seen the things until about a year ago, when out of curiosity I put a sample of "dirt" from the bottom of a compost pile into a berlese funnel separator. Lo and behold, out the bottom eventually came a horde of tiny springtails, and several pseudoscorpions. But I did not know the bit about phoresy until reading the Wikipedia article this morning.

Well I never! Thanks for the info Rik. Shame it fell off. Looked perfectly posed for what might have been a stunning high mag image to add to the set. Could it still be lurking around under the specimen mount Steve?rjlittlefield wrote: Good eyes! That looks like a pseudoscorpion.

I missed the last few posts for some reason. Very cool that I got a Pseudoscorpion and didn't even realize. They have venom fangs at the ends of their chelae (claws). The chitinous exoskeleton part of the chelae are made from metallo-organic compounds.
