Little yellow spider with black spotin the greenhouse?

Yesterday I discovered a large cluster of little yellow spiders on my borlotti beans in the greenhouse. They were easy to see so don't think they are the dreaded red spidermite or am I wrong? They appear to have one black spot. Are these a pest?

The red spider mite is so tiny it's very hard to see the whole little beastie, never mind any spots on it!

Yours are probably a harmless type of garden or house spider.

They are probably baby garden cross spiders -- they will eat masses of flies in their lifetimes 

Lovely photo Alastair 

I love these little beasties 

struth Alastiar - what camera did you do that with?

Canon 40D with a Sigma 105mm 

I'd forgotten this one from last year.. it's what they'll grow into..



.. they're a really beautiful spider when you look closely at them.  It's quite obvious in the adult how they get the name of the Garden Cross Spider.

Thanks Alistair. These are the spiders. At least I've nothing to worry about. Although they do absail onto my my head.

I so didn't need to see that second photo *shudder*

Glad you managed to get them identified though
