Small Beetle

Bit of an emergency blip  -  actually completely forgot about blipping. Worked in garden all day  -  mostly clearing nettles. I think this beetle must feed on them, but I've toured google quite extensively and found no matches, although I thought it would be easy because of the yellow triangle on its body. Maybe you can help  -  it is only about 5mm long!  Read up on Minimalist Photography in this week's Amateur Photographer   -  thought this might fit the bill:)
