The triumphant return of #MiteMonday!

Spotted this unusually reddish penthaleid mite on a decaying tree stump. Note the small pale #DorsalAnus on its back towards the rear of the abdomen.

went to the park and flipped a log which was in icy ankle-deep slush but still yielded the usuals.

Still the depths of winter here. I have been having dreams about bugs. I recently had a dream about finding plump whirligig mites everywhere: some their usual orange-red, others greenish because they had just eaten something green…I miss the mites.

Here are some whirligig mites I found a couple of years ago on a rock down by the lake, fighting over a dead midge. #iNaturalist observation: https://www.inaturalist.org/observations/225382565 :inaturalist:

Been a long time since I posted anything for #MiteMonday, but I was going through my camera and found this one I don't think I've shared before! Just a good old _Allothrombium_ red velvet mite.

#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.

#Arachtober 25: now for something entirely different, a penthaleid mite (https://bugguide.net/node/view/263374) feeding on a dandelion leaf. Species like the common _P. major_ (which this probably is) have a #DorsalAnus and excrete these globules as they feed, often hanging upside down on the undersides of leaves or vertically on blades of grass.

(If you think a dorsal anus is wild, certain astig females have secondary dorsal genital openings for copulation.)

#Arachtober 23: witnessed some interesting behaviour between two long-legged velvet mites (family Erythraeidae, likely genus _Balaustium_) on a tree trunk. They were circling each other and drumming their legs, similar to what I've seen courting _Allothrombium_ red velvet mites doing. I am going to email a mite expert and see what they think!

Unfortunately somewhat shaky video here: https://youtu.be/eGYU6fMfm_Q

#Arachtober 20: a tiny oribatid or beetle mite, likely suborder Mixonomata (https://bugguide.net/node/view/238862), ubiquitous dwellers of soil and leaf litter, armoured decomposers.

It's another #Arachtober #MiteMonday! Here's a whirligig mite (family Anystidae) cleaning its feet. Warning: handheld video! I was able to stabilize it a bit but the camera still moves around.

gotta stay on brand

here's a sidewalk mite (_Balaustium_) feeding on some predatory mite, Rhagidiidae or Cunaxidae or thereabouts; and an _Admestina_ jumping spider I found near pine trees in a nearby park. I find such interesting arthropods around pines that I don't see anywhere else.

And just as I got home I saw a snout mite (family Bdellidae) feeding on a springtail on a patch of lichen, and had to go in and get my light and clip-on lenses to get a proper photo.

Down by the lake I noticed a mite that seemed small for a trombidiid and large for an erythraeid…only on looking more closely did I notice that its dark red body had a gorgeous iridescent blue-green sheen! I think this may be a _Balaustium_ species, but not one of the ones I usually see. I've only seen this kind once before!

Happy post-postscript: today I learned by very carefully pulling the floret petals apart, I could easily free most mites.

Pic 1: whirligig mites stuck on milkweed, circled in magenta.

Pic 2: a rescued whirligig mite drinking on a tissue I put a bit of water on.

OK, sequel to my post almost exactly 1 year ago about milkweed pollinia…I discovered something amazing!

I was looking at some milkweed plants that had just started flowering and noticed a honeybee trying to get its leg unstuck from a flower. Because it's Peak Anystid, there were also many whirligig mites running around on the flowering umbels. These mites almost never stay still, yet one *was*. Could it also be stuck? YES! It was struggling to get out.

I looked carefully at more of the flowers and found a dead whirligig mite, also with its leg stuck in a flower.

I wonder how many other arthropods accidentally fall prey to the flowers?!

Whirligig mite tug-of-war commenced. (2/2)

Another vignette from Peak Anystid: any mite with a desirable morsel risks moochers trying to steal it for themselves. These two pictures were taken about 5 minutes apart—note how the first mite turns greenish from eating the bug. (1/2)

#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

#Mitestodon #MiteBehaviour #mites #Acari #Acariformes #Anystidae

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.

#DailyMiteVid #Mitestodon #MiteBehaviour #arachnids #mites #Acari #Acariformes #Parasitengona #Erythraeidae

I am also very excited because in the past few days at this one spot in a park I've found mites that I *think* are family Erythracaridae, in the same superfamily as whirligig mites. This is exciting because I've never seen them before and they are not often observed in this region. Waiting for BugGuide to classify the photos.

#DailyMitePic #Mitestodon #mites #Acari #Acariformes #Prostigmata #Erythracaridae?

In other news, we have reached Peak Anystid, that short but precious time when it seems like every leaf has a plump little whirligig mite running around on it. They are avid predators and eating is practically the only time they stay still. Here are several from the garden.

Happy #ThripsThursday! To everyone except this thrips on a fallen peony petal who was promptly eaten by a whirligig mite. I 🧡 my whirligig mites.

#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.

#DailyMiteVid #Mitestodon #arachnids #mites #Acari #Acariformes #Parasitengona #Erythraeidae

Is there an entomologist on the line? I have noticed at least 3 different bumble bees with this strange pale mark on the back (it's difficult to see clearly because they're never still).
I *think* it might be a kind of mite (varroa?) , they clearly feel it because I could see all the bees were stroking it occasionally with a leg, but they still continued flying and feeding. This was the best of about a hundred photos I tried to take with my phone!
Any clues what it is? @thebeeguy #bumblebee #bees #mites #Mitestodon

Edit: new photo crop might be clearer

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

#DailyMitePic #Mitestodon #arachnids #mites #Acariformes #Prostigmata #Erythraeidae #Anystidae #Bdellidae

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. 💧

Little red mites of spring!

- A larval sidewalk mite (_Balaustium_) eating pollen
- A young whirligig mite (family Anystidae) eating clover mite eggs (the little reddish balls)
- Sumo mites (_Allothrombium_) wrestling
- and lastly, a clover mite (_Bryobia_), which isn't really that red when full grown but which all of the other mites are frequently misidentified as. They won't be out much longer, they go dormant in the hot months.
