#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.

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

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).

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. 💧

#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.

#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!
