Let's kick off #Arachtober with some fall colours!

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

#Arachtober 22: a hobo spider, _Eratigena agrestis_ (I believe), found in a big willow tree down by the lake. These European spiders are imports to the Pacific Northwest but there are a few isolated populations elsewhere, like here in Toronto. I always get a kick out of seeing them.
Contrary to popular North American belief, they are not medically significant. They are close relatives of the native, equally harmless, and far more abundant grass spiders (genus _Agelenopsis_) and make the same flat webs with funnel-like retreats.

#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

It's still #Arachtober 24 somewhere: a tiny, curious zebra jumping spider (_Salticus scenicus_). It even gave me a little head tilt. WARNING: very high levels of cute

#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 27: late October, we're getting frost warnings, but the orbweavers just keep on trucking. Taken just a few hours ago on a grocery run; the supermarket's large windows attract a lot of midges and are great scaffolds for the ubiquitous _Larinioides_ orbweavers.

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

#Arachtober 29: didn't have time for a proper spider outing, so hopped over the garden wall to see what I could find in the yard—and almost walked right through this cross orbweaver's web strung between the dead coneflowers and columbines! As you can hopefully see in the close-up, her jaws are full of a big lump of mushed-up bugs.

#Arachtober 30: a lovely female hacklemesh weaver (_Amaurobius cf. ferox_) out in the open one night, rare for them. They spend most of their time in crevices in retreats of fuzzy back-combed silk that extends some way outside, letting them sense prey passing too close. People typically encounter the mature males that go wandering in search of mates and inadvertently end up inside.
The family is closely related to the funnel-weavers (family Agelenidae).

#Arachtober 31: handsome little ice cream sandwich boi (male _Hentzia palmarum_ jumping spider) spotted back in August.
Damn, posting every day feels like way more work than it should. Anyway back to slightly less frequent arachnid posts tomorrow…
