I don't have any fresh #Arachtober spider pics since it was raining all day, but here's an old one instead!

It’s #arachtober! Here is a Sylvan jumping spider, Colonus sylvanus, from April.

Mostly black spider with red highlights around eyes and head, white stripes running down edges of body, on a green leaf.

#Arachtober 1: the lights on this pedestrian bridge create giant spider shadows! The casters are the appropriately named bridge spiders, _Larinioides sclopetarius_.

#DailySpiderPic #spiders #orbweavers #Araneae #Araneidae

A pedestrian bridge by night, with downward-facing lights set underneath the wooden railings. A spider has built its web directly beneath one, creating a giant spider shadow on the walkway.

A further-out view showing the bridge curving away, with dozens of similar lights.

An orbweaver spider at the centre of its symmetrical, wheel-like web. It has a darker leaf-like marking (the folium) on the top side of its abdomen which looks a little like a fleur-de-lys.

It's the first day of #Arachtober, a celebration of arachnids!

I love sharing art, photos, and information about our eight-legged friends, but if that's going to stress you out you may want to mute that tag.

However, consider learning more about the incredible creatures that share our world!

I am told that it is #arachtober

A giant spider? A tiny moon?
A Spotted orb web weaver has been spinning a productive web three mornings in a row. #Arachtober

A spider is wrapping up a snack for later in spider silk. A waning moon is seen beside the spider and seems about the same size in a blue morning sky.

This month, #Cheliceratime will be under the banner of #Arachtober!! :D🕷🕸🦂

For the occasion I prepared an arachnid-only planning, with various groups and cool topics about these critters, the post coming this Saturday 03/10 being a absolutely massive project finally making its way here!📚

#arachtober (my favourite of the portmanteaubers) upon us again! Here are some spiders in my house and outside it!

A spider web coverd in perfect orbs of dew. There are green and orange leaves in the background.

A rust red deck where an egg sac of adorable baby orb weaver spiders has just hatched. Some of the spiders are in focus, some are not. They are all busy discovering the world.

Close up of an orb weaver spider, (the kind with the cross on their back ) chilling in their web. There is blue sky in the upper half of the photo, and blurry green trees in the lower.
