Found this in my room and haven't seen anything like it before. It was about 4-5cm long and has wings. Flew away before I could get a better picture. Photo taken from the Midlands, UK

Short description of Leptoglossus occidentalis:
Western Conifer Seed Bug The Western Conifer Seed Bug Leptoglossus occidentalis is a large and conspicuous squashbug, reaching a length of 20mm when adult. It is easily distinguished from all other GB coreids by its reddish-brown body, transverse white zigzag line across the centre of its wings and characteristic leaf-like expansions on the hind tibiae.
