This was found crawling on the rain guard on an operating MV light trap. When back lit there were two obvious things inside the body, illustrated with arrow. Any idea what these are (internal organs of some kind?)

Reared on on grass and has now pupated (29/5/2012) and subsequently eclosed (16-17 June 2012). Large Skipper as Michael suggested.
