#prostigmata — Public Fediverse posts

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.

#Arachtober 28: clover mite (_Bryobia_) in a bright patch of lichen.

#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 21: dreams can come true (if your dream is finding a snout mite https://flipping.rocks/@nev/115403746846167689)

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.

#Arachtober #MiteMonday: just a good old red velvet mite (_Allothrombium_).

Just imagine having a guinea pig-sized one, as a pet. It would be soft and squishy. It would enjoy squeezing into little crevices to nap. You could brush it, very gently. It wouldn't see very well. It could climb up things with little retractable claws. You could probably feed it mealworms.

#Arachtober 2: anystid renaissance! Commonly called whirligig mites for their constant frantic and erratic running, these large (~1 mm*) predatory mites in the family Anystidae have a population boom in early to mid-June and seem to increase in numbers again in autumn, at least around here. They eat aphids, small midges, each other, etc. This one seems to be eating some kind of barklouse (Psocodea)?

* Given that many mites are microscopic, any mite one can clearly see with the naked eye counts as "large".

Anyway, #InternationalRockFlippingDay finds: a vine weevil (*Otiorhynchus* of some kind), and a bryobiine spider mite, see e.g. *Petrobia*.

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.

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.

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.

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

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.

#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!

#MiteMonday: it's that time of year again! A sheet-web weaver's web in a willow tree crevice is carpeted with tiny _Bryobia_ clover mites.

#Arachtober 21: Happy #MiteMonday! Here's a snout mite (family Bdellidae) snacking on a long-legged velvet mite (family Erythraeidae). Taken back in June.
