Usually abundant in forest leaf litter, can be extracted using a home-made Berlese Funnel HERE.
This specimen was removed from the leg of a fly; pseudoscorpions are phoretic.
Microscope slide temporary mount. Length: 3.6mm from tip of chelicerae to end of abdomen.
Top image: Whole specimen. Note the Pedipalps - large pincerlike appendages have poison glands opening at tips for capturing and killing prey.
Bottom image: Close-up of Chelicerae
At the front of the body are the Chelicerae - small claspers for holding prey while feeding. The moveable outer finger has a spinneret near the tip involved in silk production.

Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
