💁🏻‍♀️ ICYMI: 🕷️🦉 According to entomologist George McGavin, the massive whip #spider in #Guyana's #tropical #rainforest is the ultimate animal for hunting in the dark.

Flattened, fast, and equipped with spiky palps and incredibly long sensory #legs, there is no escape for #prey trapped in its spines.

“ #Mites & #spiders are #arachnids and they eat each other, they also have toxins in their #venom that target each other. Spider venom #peptides "organic" way of killing mites doesn't accumulate in the food chain; doesn't kill the farmer or the beekeeper or any pets — it's selective to the #varroa mite," Dr Herzig said.

(Note 1,700 native bee species have a very different biology from European honeybees.

#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.)

Did you know? Tiny penthaleid mites will sometimes wear water drops as hats. 🥰

(That's a total fuckin' lie, it's their excrement. Their anuses are located on their backs.)

#Arachtober 31: yesterday I was enjoying the unseasonably warm weather down by the lake when I passed the little patch of willows where I learned I could find lots of _Penthaleus_ (a.k.a. earth mites, winter grain mites, blue oat mites etc.) on the grass in the spring. On a whim, I got down in a patch of grass and checked again. Not as many as in the spring, but they were there!! I wonder if they can be found year round, or if they are dormant during high summer like they are in hotter climates?

As you can guess, these mites are herbivores. One has a drop of some excretion coming from its #DorsalAnus. (They spend a lot of time on the sides of grass blades and the undersides of leaves; it must come in handy.) The mites are all female and parthenogenetic.

I've been obsessed with arachnids for like 10 years now and there's still so much I don't know, even about the common species in the spots I visit regularly! There's always something new to learn. Take a closer look at the world around you and you'll be amazed by what you can find. Many thanks to everyone who's followed along this month!

Happy #MiteMonday, yes I've got another penthaleid and I'M NOT SORRY. In this photo, I like how the little blob of excrement coming from its #DorsalAnus casts its own little shadow.

It's been colder and snowy these past several days, and the winter grain mites (family Penthaleidae) are back!

Yesterday went down to the lake to the big willow tree where I'd found a winter grain mite years before and found a whole bunch of them! This is the first one I saw.

I got up to see a young woman watching me. She correctly guessed I was looking for bugs, and I showed her the piece of bark and explained that winter grain mites are neat because their anus is on their back. She thought it was very cool and said something nice about the vast unseen miniature world. In return she told me that dragons (I'm pretty sure I heard her right) do not have anuses *at all*. I'm afraid to Google this so will just take it on faith.

I am sad and angry over trees next door being cut down so I had a croissant and took a LOT of bug pics and now I'm going to take a sad nap :blobsad:

- baby zebra jumping spider (_Salticus scenicus_)
- long-legged fly (_Condylostylus_?, family Dolichopodidae) on hostas
- bumblebee (_Bombus_?) on coneflower
- pseudoscorpion (Cthoniidae? Neobisiidae?) :pseudoscorpion:

A bit of #OpenAccess #Arachnews:

How do forested buffers around rivers affect the diet of predators like trout and spiders? In the abundant fall season, both get most of their food from terrestrial sources! I'm not sure exactly what this means because ecology is really hard so read the paper yourself: https://www.sciencedirect.com/science/article/pii/S2352249623000319#s0040 :OpenAccess:

Two new species of eyeless, cave-dwelling pholcids described. One is from Australia's ancient Pilbara, a remnant from before Australia aridified. Another is from lava tubes on Réunion Island. Plus some philosophical questions about what a cave is, really. https://subtbiol.pensoft.net/article/105798/ :OpenAccess:

However, I was *really* there to catch some rays with the wolf spiders. This _Pardosa lapidicina_ had such a comfortable sploot going on that she didn't even mind me taking up-close photos. There's no sploot like the P. lap sploot.

#MiteMonday: on the way back from the Spit, stopped to check blades of grass for clover mites and instead found this equally tiny earth mite (family Penthaleidae), with its unique #DorsalAnus! This is the only pic I managed to get.
