"Flies (Diptera) are particularly suitable transport hosts. They are highly mobile, capable of long-distance flight, and frequently visit the same types of transient habitats that pseudoscorpions depend on. By attaching themselves to a fly, pseudoscorpions can effectively outsource dispersal – reaching new habitats they could never access on their own."

#Pseudoscorpions are #interesting and #biologically diverse #arachnids that are often overlooked due to their #smallsize. Many species are #grounddwellers or live in deadwood. The largest #taxon is the #Chernetidae, with approximately 726 extant #species. L. Laibe et al. (2025) described a new species of its genus #Attaleachernes from the eastern #Amazon region and also characterized the #habitat.

This person has discovered over 1000 new species in their lifetime. Hats off!

How many spiders and pseudoscorpions does it take to make one of the world’s greatest taxonomists?

Former Perth curator Mark Harvey is one of the few people on Earth to have described 1,000 new species, many of them arachnids. Colleagues say his legacy is ‘unquantifiable’

#Arachtober 5: the last order of arachnids I have found, pseudoscorpions! They look kind of like scorpions without tails; they are found basically everywhere on earth but Antarctica, but they are absolutely tiny and live in places like under tree bark, under rocks and logs, in leaf litter, etc., so you will rarely see them unless you're looking for them. Sometimes they can be found clinging to the legs of larger flying insects with their little claws, or indoors eating booklice and other tiny household insects.

The ones in my garden are so small you might take them for mesostigmatid mites at first glance. This one has captured a soil-dwelling mite of some kind.

The rain this morning brought out plenty of arthropods in the garden, including these two arachnids. A podocinid mite (https://bugguide.net/node/view/247922), a tiny mesostig with extremely long, thin front legs terminating in forked hairs; and a chthoniid pseudoscorpion, with its clawed pedipalps. Strangely akin.
