I was just in the process of cutting up a lettuce ready for washing, and when I moved the leaves over to the sink, this little fella was on the side. 99% sure it came form the lettuce. The lettuce was sourced from Spain and I wondered if this is common in the UK.
It's a philodromid spider and, from the long spear shaped mark on the abdomen, I'd guess at a Thanatus species (but can't rule out a Philodromus). There are two UK Thanatus species, one very rare and the other not much like yours. So, I suspect yours is from Spain not the UK.
Thank you Jag.
I will now be contacting my supermarkets customers service's with a bit more information.
I am glad you picked up on the markings. I meant to mention that in my post. I was surprised that such a small spider had such distinctive marking when seen up close.
Can I just ask, what is you background?
Hi Adrian, I'm an ex agricultural entomologist and have had an interest in spiders for 30 years or more.
Re your spider - philodromids don't have a reputation for being poisonous or dangerous so I wouldn't get your supermarket too alarmed. It may have helped to remove any aphids off the lettuce!
Thanks, I was curious as to what type of experts come on this site. I think this site is an excellent tool, really impressed with it.
I wasn't overly concerned about alarming my supermarket, I just wanted to let them know.
I just really wanted the spider to be foreign to be honest, as I thought it would be cool.
I have taken the offending lettuce and the spider back to the supermarket and they are going to look into it and reply accordingly.
Thanks for your help though, its been fun.
