Crappy photograph I took of Adam the jumping spider.

I have a tiny jumping spider that lives in my office . It’s about 7mm long and is very active. I managed to take a crappy photograph of him (I think it’s a male, females are a bit bigger) which you can see above.

I see this spider regularly, so it’s probably spiders plural, but since I only ever seem them on their own I think of it as just one.

My iphone identified the species as Hasarius adansoni. I think this looks about right. Here is an image of the species from Wikimedia:

A pretty good match I think. I uploaded the photograph to ChatGPT o3 and it spent almost three minutes thinking about then, concluding that it’s that thinks it’s the Zebra Jumping Spider Salticus scenicus. I don’t think that’s right at all, they have lots more white stripes.

Anyway, I am calling him Adam. He is very welcome.
