#DailyMiteVid: whirligig mites (family Anystidae) are happy to eat each other, as you can see from this clip filmed today. I noticed that the mite being eaten seemed to still be alive and moving its limbs; it was only on re-watching the video that I realized it seemed to be cleaning one of its legs!

CW: slightly shaky video moving in & out of focus; mite being altogether too chill about being devoured alive by its fellow

The sidewalk mites (_Balaustium_) that swarm over the ground this time of year primarily eat pollen, but they will also scavenge dead bugs (I do not think they are actually predatory). This horde has found an ant pupa, I think?

I am fascinated by this behaviour and try to catch it at least once every summer.

#MiteMonday: ever look down and see a bunch of little red guys on the pavement or whatever? Chances are they're long-legged velvet mites (family Erythraeidae) in the genus _Balaustium_. Practically all of their relatives are parasitic on other arthropods as larvae and predatory as adults, but some common _Balaustium_ species are lifelong pollen-eaters. Here's one eating peony pollen I put down.

It's still #MiteMonday somewhere…

Vignette from under a log. A snout mite (family Bdellidae) feeds on the remains of a springtail, with a guest appearance from a beetle mite (order? suborder? Oribatida)*.

* Above superfamily or so, mite taxonomic ranks start getting contentious.

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

10 seconds of mite sex why not ⁦¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯⁩

I can't even wait for #MiteMonday, this is too exciting, I have to share it now!!!

In Walter & Proctor's _Mites: Ecology, Evolution and Behaviour: Life at a Microscale_, there's this great image of mites in the family Acaridae mating, with the male facing backwards and his aedeagus (dick) inserted into the female's dorsal copulatory opening (bussy [back pussy]), so he is carried along on her back, a bit like a wheelbarrow race, but backwards.

Anyway this evening I was idly taking macro of the mites in the fruit fly culture when I SAW IT. It's easier to make out with video.

marked nsfw for graphic photos and videos of mite sex, you were warned
