  1. #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…

  2. noch schnell die letzte gelegenheit nutzen #arachtober an den #DailyBug zu tackern

    Hornweberknecht
    Phalangium opilio

    keine #spinne aber ein spinnentier, ein arachnid, also passt #arachtober da trotzdem.
    anders als spinnen haben weberknechte keinen klar zweigeteilten körperbau mit vorderkörper, wo die beine dran sind und hinterleib, wo die spinndrüsen drin sind, sondern das ist alles "an einem stück"

  3. Si vous voulez permettre à un docu super cool (si si, promis !) sur une araignée presque inconnue de la recherche et qu'on a vue une seule fois en 200 ans, allez regarder le lien vers mon nouveau projet et surtout partagez-le autour de vous ! C'est super important, c'est difficile d'avoir de la visibilité sur un sujet comme celui-là :D

  4. #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).

  5. #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.

  6. CW: Hairy spider... but friendly looking

    Cookie monster

    Araignée loup - Dock spider - Dolomedes striatus

    I spent an entire week looking at that spider at the end of a dock on a lake. It was the size of my palm 🫣 I was fascinated how it froze at night and came back to life in the morning. Most of my macro pictures are horrendous to look at! This is the only one that made me laugh. A little.

  7. CW: spider

    #Arachtober

    I was in my garden, where there was no breeze and nothing else moving, and this Red-femured Spotted Orb Weaver was swinging using its web.

    There was also no music playing.

  8. #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.

  9. #Arachtober 25: now for something entirely different, a penthaleid mite (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.)

  14. 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

  15. 'Zahlen: Acht' #FotoVorschlag

    ich habe mich jetzt aus den vielen bildern von achtbeinern für's erste für dieses entschieden, zum einen, weil der arachnophobie-trigger-faktor für viele bei diesen weberknechtartig aussehenden zitterspinnen weit geringer ist als bei anderen, zum anderen weil die beiden so süß eine liegende 8 mit ihren beinen formen :3

  16. #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: youtu.be/eGYU6fMfm_Q

  17. #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.

  18. #Arachtober 19: for spooky season, here's a couple of ghost spiders (family Anyphaenidae)! The first is an adult, possibly the mother of the tiny one in the second photo. They resemble sac spiders like _Clubiona_ and _Cheiracanthium_ but with distinct patterns of markings, and as you can see they make similar silk hammock retreats, here under the leaves of a _Silphium_ cup plant.
