Blue Shieldbug

I'm a fan of shield bugs generally. They're such a pleasing shape. Yesterday I was putting a mass of dried weeds into the compost bin and found this little beauty - Zicrona Caerulea!

He was easy to spot, but not so easy to photograph. I identified it through the excellent British Bugs website. It's a predatory bug so I'm thinking not that unwelcome on the allotment, as long as he predates the bad guys!
