For #MiteMonday: mites eating things.

1. Long-legged velvet mites (family Erythraeidae, probably _Balaustium_) eating a midge
2. A whirligig mite (family Anystidae) eating a globular springtail
3. A snout mite (family Bdellidae) eating a barklouse

A dead midge on a rock, with several fuzzy, oblong red mites clinging to it.An orange mite with a star- or asterisk-like arrangement of spiky legs feeding on a small round black springtail. It is on a rough black surface and there is not enough light, so the mite is rather washed out.On a pine tree, a red-orange mite sticks its pointy, weevil-like snout into the face of a yellowish barklouse.

Bonus #MiteMonday: a _Balaustium_ sidewalk mite feeding on pollen from a horse-chestnut flower (which I put down to attract them and get photos).

These mites can be found in great numbers this time of year, very visible on surfaces like concrete and bricks, hence the name. As well as pollen and sap I've seen them feeding on dead bugs. Some are purely raspberry-red, others have this longer white coat or just white patches, others have a gorgeous blue-green iridescent sheen.

The pair of red protuberances are not eyes but special structures called urnulae, which secrete various useful substances like a defensive chemical/alarm pheromone, and a "waterproofing" compound that prevents their cuticle from drying out (useful as they spend a lot of time running around in the sun).

A dark red mite with long legs and a short white velvety coat, just in the middle of feeding on a clump of bright orange-red pollen on a paving-stone. It's dwarfed by the long curved white stamen of a horse-chestnut flower, topped with a very large mass of pollen.

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.

Belated #MiteMonday: it's the time of year I start carrying a little water dropper bottle for the whirligig mites. I've found it's a reliable way to get them to stay still for photos. đź’§

#MiteMonday: this weekend I got out to my sumo mite (_Allothrombium_) tree to catch some wrestling bouts!

It is some kind of sexual competition thing: certain males seem to stake out a little patch and aggressively defend it against all comers. The females, I think, are the larger ones who take little notice of the fights and mostly wedge themselves into crevices in bark? Courtship rituals seem to involve leg-tapping and walking around each other in circles. I am wildly curious about what's actually going on.

Two red velvet mites, plump, wrinkly mites with broad "shoulders" and narrower butts, start to grapple on a lichen-speckled tree root shaded by grass.Another pair of mites try to grip each other with their long front legs, just like sumo wrestlers. Their fuzzy pelts are easier to see in this photo.One mite tries to sink its pedipalps into its opponent. They're also on a near-vertical surface.The hollowed, gnarled tree root in the grass where all these dramas are taking place. If you zoom in you can see a number of mites near the centre. They are about 2-4mm in body length.

#MiteMonday: a red velvet mite (_Allothrombium_) sneakily snacks on midges from a spider's web. I also saw a red-winged blackbird eating a midge-filled spiderweb, too. At this time of year, the few spiders that overwintered catch so many midges that their webs almost collapse under the weight—more than they could possibly eat. I wonder how much midge biomass these spiders inadvertently make available to other animals!

I almost forgot it was #MiteMonday! Inspired by @zorbama's shot of a running crab spider, clover mite, and midge all together (veganism.social/@zorbama/11437), here's a running crab spider (_Philodromus_) I found feeding on a clover mite (_Bryobia_). I don't actually often find many arthropods feeding on the adults, though I've seen predatory _Anystis_ mites eating the eggs.

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).

A teardrop-shaped red-brown mite with a small translucent white thing in its mouthparts. It could be mistaken for an ant pupa but I promise it's a springtail.The same mite and its prey are dwarfed by a small slug also on the underside of the log.Another white springtail, this one identifiable as a poduromorph, comes face-to-face with a light brown mesostig only a little longer than itself. The mite's front pair of legs are long and thin, used a bit like antennae.

The first #MiteMonday in a while! The wet dead leaves are a bountiful source of predatory mesostigmatid mites.

#MiteMonday: wintertime rock flipping turned up some penthaleids and those iridescent purple springtails, not quite sure what they are. They were about the same size (see third photo).

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.

A small teardrop-shaped red-brown mite with thick, claw-like second legs and long thin antenna-like first legs crosses a velvety mat of fungus towards a wet dead leaf.A similar-looking mite (you can see the differences in the legs better from this angle) on a broad, cratered and rippled mat of fungus with variegated patches of beige, yellow-brown, and dark brown, with black specks all over. There are no other visible large lifeforms.

#MiteMonday: checked out my favourite dead logs, got more pictures of mesostigs preying on springtails!!

#MiteMonday, perhaps.
Not entirely sure these are mites, as I know next to nothing about them.

#iNaturalist thinks it might be Linopodes.

Saw them when I turned over a piece of rotting wood to have a better look at the bottom of the fungi growing on it.

#arthropods #mites #fungi #nature

A very small light yellow arthropod, probably a mite.Close up of the bottom of a bracket fungus growing on a piece of rotting wood.

The overall colour is brown but with lighter and darker patches. There is a fine network of little holes. In some of the holes you can see tiny water droplets. There are also quite a few tiny mites running around.Small yellow mite on a piece of wood. The wood is a warm light brown with some black stains and one rather large white patch (I'm guessing some kind of mold).Bottom of a bracket fungus with vertical pores.

#MiteMonday: Astig explosion!!!

I had been putting off making a new tub of fruit fly medium and excelsior for the flightless fruit flies, and discovered the other day that the current tub had quite the population of astigmatid mites, feeding off the same stuff and emerging in great numbers to swarm the outside of the tub during the warmest part of the day. I was actually pretty excited about this, as I hadn't personally seen an infestation of these since childhood, long before I started doing smartphone macrophotography (as a matter of fact, long before smartphones existed, but anyway…), and posts about them on bug ID forums are, for some reason, virtually always low-res shaky videos. So I actually had a chance to get up-close photos!

Astigs, which branched off from oribatids, are a large and diverse group. Some common species, largely in the family Acaridae (like _Acarus siro_ and _Tyrophagus putrescentiae_), are found around the world as pests of stored products. They may be called "grain mites", "mold mites", "flour mites", "cheese mites", etc. They are harmless, though in huge numbers (e.g. in a bakery, barn, or grain silo) they can spoil food.

I had just been using a pantyhose sock thing to cover the fruit fly tub, but I went out and got surgical masks so I can make something less porous. I'll also make a fresh batch of fruit fly medium and toss the old tub. That should help keep the mites at a more manageable level.

I can't ID these precisely—you really need an expert with a key and a microscope—but they're likely Acaridae of some kind.

A loose line of small white mites crawling along the outside of a 32 oz. (945 mL) plastic tub containing fruit fly medium, a light brown paste. A fruit fly pupa, an elongated reddish-brown case, is buried in it.One of the mites up close. It is translucent and almost colourless, with short pointy legs and sparse but very long hairs, especially on its butt.Another mite up close. Its front two pairs of legs point forwards and the back two pairs backwards, although they are a bit more evenly spaced around the body than the legs of, say, red velvet mites. The body is roughly oval, with a higher ridge down the centre with grooves on either side.A mite crawls on the outside of the container. On the inside, several much rounder, smoother-looking and somewhat smaller mites—probably an earlier life stage—line a tiny tunnel or cranny that has formed in the fruit fly medium.

🚨 MITE ON MITE ACTION 🚨

This orange, alien-looking predatory mite is in the family Labidostommatidae, and has proudly caught a tiny hard-bodied mite (Scheloribatidae) to eat.

BUT it's not easy to crack through an oribatid mite's armour, which is probably why it was constantly carrying it around instead of eating it!
