#Arachtober 10: 10/10 is #InternationalJumpingSpiderDay! °OO°

Jumping spiders have a pair of large, keen eyes that give them their distinctive appearance. These eyes can see colour and fine details, whereas the smaller, simpler eyes that ring their heads are […]

A female jumping spider being courted by a male on a worn log fence. They are both mottled brown, with the male being a warmer lighter shade. I'm not sure of the genus or species...

I totally spaced out on #Arachtober yesterday, and today it’s world #JumpingSpiderDay. A female Apache Jumping Spider, Phidippus apacheanus, with sawfly prey, on the restroom at Cottonwood Picnic Area, Cimarron National Grassland, near Elkhart, Kansas, USA. #bugsky #bugwatching

#InternationalJumpingSpiderDay you say?! A chance to share a photo of Zoey the Zebra Jumping #spider from earlier in the year, when she was living in our porch. Here she was climbing down one of the window panes. #arachtober #wildlifefrommywindow #invertebrates

A spider stands on a shiney black surface, staring at the camera with two large black eyes. She has two slightly smaller eyes to the outside of the main ones that give her her cute appearance. She is covered in dense hairs that give her a mottled appearance made up of white, blakc, and light brown colours.

Thank you, Beck! Happy #Arachtober! Hearing from you reminds me of my time on Fanimals, which I still think about with a lot of fondness 🕷️
P.S. when I took that photo, I somehow had to hold the heavy camera with one hand while holding the spider on the other!!

Today, October 10, is International Jumping Spider Day, and it is also #Arachtober! I thought I'd mark the day by sharing this photo of a little Portia africana male on my hand. These little spiders have touched my life in so many ways 🕷️ #InternationalJumpingSpiderDay

#Arachtober 10th is also #JumpingSpiderDay.

I found this Bold Jumping Spider (Phidippus audax) while doing the #CityNatureChallenge with my girlfriend. She had to help me get prickly pear spines out of my pants shortly after this shot.

I've been severely lacking in my #arachtober duties, so I thought I'd finish what I left halfway last year - an A to Z of arachnid genera.

A for the inimitable Argyroneta (Argyronetidae), the only spider known to live an entirely aquatic lifestyle.

Macro of a female green lynx spider guarding her large, spiky brown egg sac underneath a green leaf. She’s a vibrant, translucent neon-green head and body, while her long, light tan and green legs are covered in distinct black spots and prominent, sharp black spines. Her legs wrap securely upward to anchor onto the textured, papery brown surface of the egg sac suspended above her in a network of fine silk. The background is completely dark and dissolved, isolating the protective mother.

Black and yellow garden spider, Argiope aurantia, making a stabilimentum in her web. Different Argiopes have different types of these. There are a lot of hypotheses for why they make them, but no consensus yet. Not my video.

I'm betting a lot of folks here have seen the Black-and-Yellow Argiope (Argiope aurantia). As kids we called them Writing Spiders.
