Black walnut gall, a pretty good specimen found in our backyard 😮

I saw a bunch of these mites walking around on the table, they kept occasionally stopping to nibble on something like this one eating some kind of detritus. I think they might be whirligig mites based on the erratic circles they kept walking in

#Sarcoptes #scabiei var. hominis (#Astigmata, Acariformes) is a skin-#parasitic #mite that feeds on human #epidermal cells. Infection typically occurs via adult, mated #females.The mite has #subspecies found on both #domestic and #wild #animals. The #evolutionary direction was via #humanancestors to humans and from there #spreading first to domestic animals and then to wild animals (see ref).

In summer when I was looking for galls to photograph for National Gall Week, I suspected that many were high above in the trees. Come autumn some of the leafy sort began drifting to ground...the first I noticed literally fell into my lap as I was sitting for a coffee break while woodcutting! That one is yet to come, this one came along the next day (mid October). Possibly Poplar Gall Mite Phyllocoptes populi, on a leaf of Populus balsamifera Balsam

It's week 3 of fatherhood, and today I was granted special dispensation from shopping, housework, nappies and feeding, to do a brief spot of macrophotography in the sunshine, brilliant!

The highlight was this incredible Oribatid mite, sporting long defensive spines (Neotrichozetes spinulosa). I've nicknamed it the Hellraiser mite, which seems to be catching on - feel free to use it too!

In my new YouTube #video, I tell the #hypothetical story of a #Histiostomatidae #mite that lived its #lifehistory in the #dung heap of the #dinosaur #Edmontosaurus #annectens during the Late #Cretaceous. It developed #fungivorously within the dung and, when conditions deteriorated, was #transported by #flies to a new habitat (phoresis). All images and footage created with #AI assistance, except photos of free-living mites.

This little beasty popped out from between the gills of a 'shroom I was trying to photo. A Moss Mite I'm told , something like Damaeus onustus.

Why a #mite of the #Parasitidae (#Mesostigmata), apparently genus #Parasitellus, seemingly attacks moth #Pyrausta #despicata (Crambidae). Parasitellus develops in #bumblebee #nests and uses them for dispersal (#phoresy) to other nests, thus they leave their hosts on blossoms and wait for new hosts to be carried to new nests. The moth was detected by the mite as a #nonsuitable #phoretic #host.
