  1. AND THEN. On the top of the very same chair I saw a cluster of small mites that, by their size and behaviour, I first took for clover mites (unusual, since it's now kind of hot for them.) But no. They were a kind of mite I'd never seen before in real life: rodent/bird mites!!!

    No idea what they were doing there. The chair was under a tree, so I suppose a bird nest or part of it could have fallen down? No traces of one nearby, though.

    As I was photographing the mites, a bunch got on me and my phone. While these mites *can* bite humans and cause itching (although they cannot reproduce with only us to feed on), this is not a big deal to me because I currently have eczema/heat rash and my entire body itches already. There's nothing they can do to me that hasn't already been done!!!

    I'm kicking myself for not having any collecting vials on me, though.

  4. #MiteMonday: a tiny _Podocinum_ mite found under a rock. Its extremely thin elongated front legs have forked hairs at the end, and it seems to use these legs like antennae to navigate.

  8. #Arachtober 4: March mating mesostig madness!

    These are an ubiquitous sort of soil-dwelling predatory mites, likely in the family Parasitidae (ironically, primarily predators) in the order Mesostigmata in the superorder Parasitiformes. They are only very distantly related to the whirligig mite I posted the other day, which is in superorder Acariformes. While the two superorders are traditionally grouped together under Acari, it is likely they don't share a common ancestor and should be treated separately. So I'm counting them as a different group!

  12. 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.

  16. The rain this morning brought out plenty of arthropods in the garden, including these two arachnids. A podocinid mite (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.

  20. I almost forgot it was #MiteMonday! From under one of my reliable dead logs just a few days ago, a mesostig with its prey, a tiny white springtail; a slug for scale; and a smaller, paler mesostig crossing paths with another springtail (which it did not try to eat).

  24. Flipped over a piece of log on a big dead stump and there were tons of those little iridescent blue-purple springtails, but also several mesostigs. I was watching them hoping one would catch a springtail, and one seemed to be questing about for something. Then it chased after one of the other mites, flung itself on its back, and after some tumbling around ended up clinging to its underside. Then, this. I'm not even sure what's happening, I don't even know what appendages these mites use for sperm transfer.

    edit: oh yeah I forgot to add they're totally having sex

  28. Gotta post something for the last #MiteMonday of the year. Here's some mesostigs (family Parasitidae or thereabouts?), predators of the undergrowth, making their way across alien landscapes of fungus and leaf litter on the underside of a dead log.

  32. Thrilling moment today. I had flipped a log and was trying (with limited success) to get in-focus photos of this mesostigmatid mite when a tiny springtail ran directly into its path. To my surprise the mite seized it immediately and then, antenniform front legs aloft, hurried off looking for somewhere safe to consume its prize.

    I knew, of course, that mesostigs like this were predatory; I'd just never witnessed the actual predating!

  36. I decided to go back and see if I could find that beetle again and get more pictures, and I did!! While these beetles have potent chemical defenses in the form of caustic oil they secrete, this one was quite placid and let me get up close with the clip-on phone lenses, even crawling onto my hand at one point.

    The mite mostly stayed under the beetle's chin, but occasionally ran around its head.

    A passerby asked what I was looking at and I am afraid I was not the best or most observant conversationalist, as I was busy taking all the pictures I could get, but he seemed familiar with the concept of phoretic mites at least, and remarked that perhaps the mites gained some benefit or protection from the beetle's secretions.

    This BugGuide observation <bugguide.net/node/view/31709> seems similar?

  40. The best thing I saw today. On and around Hawk Hill, the low hill near the café, several beautiful large _Meloe_ oil beetles were voraciously eating green vegetation. These were a prize all on their own and I took pictures of all of them. Later, at the café, I was going over the photos when I noticed one of them had something on its face!! A phoretic mesostigmatid mite!!!!!

  44. #Arachtober 19: one of my favourite finds this year, a hister beetle (family Histeridae) carrying several phoretic (hitchhiking) Uropodina mites attached via "anal pedicels", tough but stretchy stalks formed from special secretions from glands in…well, you can probably guess where. The mites are harmless to the beetle and use it to disperse to new habitats.
