Blue bodied spider?

I keep finding small blue bodied spiders on the underside of my swiss chard, does anyone know the name of them I have googled but not managed to find either pics or any info on them?

 

Hi Golcarlilly,

I couldn't find anything about blue spiders, but I found this interesting link about pests and swiss chard: http://www.hort.purdue.edu/rhodcv/hort410/spina/sp00001.htm

 

thanks for that:thumb:
