Western conifer seed bug

Thanks to reader Kerri for sending in this picture of a bug, asking for help in identification. After some intense scouring of the web, I'm certain this is a Western conifer seed bug (Leptoglossus occidentalis) and as such it is actually fairly rare in the UK, though rapidly becoming less so. It's native to the Western USA but has been invading Europe over the last decade and the UK in the last few years, spreading from the South coast. Kerri's was found on the East coast in Lincolnshire. It is a minor pest that mostly lives in conifers, sucking at the developing seeds and causing them to fail to develop properly. Actually its name describes it quite well!
