Box Bug (Gonocerus acuteangulatus)

No, not in a box, but feeds on it and traditionally known from Box Hill in Surrey but has been spreading its range recently. When I found this striking beastie at the lakes back on 20th April I didn't know what it was and had to wait until now before my book on Shieldbugs and Squashbugs (Evans & Edmondson) arrived. Identification was then fairly straightforward, but I was surprised and somewhat pleased to discover that it is a new species for Norfolk!
