This intriguing creature was sitting behind the hasp on my garden shed door this afternoon. Fortunately it didn’t go far while I ran indoors to get my camera.
I could see from its shape that it was a jumping spider, but even smaller than the zebra jumping spider (see my post on this blog, 25th of March ). This is a male, body 3-4 mm long.

I think he’s a Pseudeuophrys erratica, a species which has a decidedly northern and western distribution: South Pennines, North Wales and parts of Scotland but described as ‘nationally scarce’ in the British Arachnological Society’s field guide.
They live on walls and piles of stones and leaf-litter. Their bodies are iridescent and, like other jumping spiders, the males use their legs in courtship displays.
To be sure that he isn’t one of the other two Pseudeuorphrys species examination under a microscope is necessary (if I can catch him!). I’ll pass my pictures on to the Arachnological society and get advice. Nice to think that I might have a nationally scarce species in my garden in Halifax!
I’ll post any more information when I have it – they’ll probably say ‘P.erratica? oh, no, nothing like it!’.
Pleased to find a lovely and interesting spider, whatever species he turns out to be.
