Happy Halloween! Hope you are enjoying spooky season and Halloween. We made a jumping spider jack-o-lantern this year! A true collaboration: the 11yo carved the pedipalps (they look like small arms near the mouth) and I carved the 8 eyes and 8 legs. Legs are tricky!
🐡🕷️
This is our Jack-o-lantern on a table on our porch. It’s made of a large pumpkin for the abdomen of the jumping spider (from which 8 legs like wide v’s are cut and affixed with toothpicks). The head in front is a smaller pumpkin with 2 large and 2 medium circular eyes are visible. There are two smaller pairs on the sides but not visible here. Below the eyes are furry pedipalps. It’s dark and both pumpkins are lit. Same double pumpkin jumping spider jack-o-lantern but a side view so you can see the smaller eyes, the legs and the wide v holes cut in the abdomen to produce the legs

Morning peeps! I’ve written a piece for @thespinoff.bsky.social on why I ended up taking legal action against my employer and a little bit about how it played out. The whole story needs a book to tell but this is a good start 😂 thespinoff.co.nz/society/01-1... thespinoff.co.nz/society/01-1...

HAPPY HALLOWEEN!!! 🎃👻
Is that a pumpkin or a spider butt? The marbled #orbweaver is all decked out for fall and the spooky season (though, really, this lovely lady was very shy and harmless)!

#Araneidae: #Araneus marmoreus

A large round marbled orange rump faces the camera. Radiating out from it are 8 striped legs. An orange marbled orbweaver spider sits on a white background facing the viewer. It has small eyes and spiky striped legs. An orange marbled orbweaver spider sits on a white background facing to the left. It has small eyes and spiky striped legs.

I noticed a quickly shutting tiny door. I pried it open to see this set of legs. Only good shot I got. Possibly a Southwestern Trapdoor Spider (Eucteniza relata). First trapdoor spider I have found. Found in South Texas.

I wanted to share this gorgeous little jumping spider for #Arachtober! This is a currently unnamed species of Trite that I found in Christchurch. Not normally found there. Amazing what can happen when you take the time to look 🕷 #LoveSpiders

Most scientists are not great at communicating their science, says Dean Pentcheff #LivingData2025. #ScienceCommunication is effective when we use narratives. Tell your story. Then you’ll get into people’s hearts. #JaneGoodall

#Arachtober 1st - Tropical Orb Weaver (Eriophora ravilla). One of my favorites. Very common in South Texas. Can be found up the East Coast of USA down to South America. This is a stereo image. Cross your eyes for 3D. 🕷️

Join us in celebrating Arachtober by sharing your #spider and other #arachnid photos all month. #Arachtober has spread around the web. We’ve created a basic site at Arachtober.com to explain what this is all about. Banner by @ashleymbradford.bsky.social, inspired by my recent linocut artwork.
