Wow, nice find. It's an adult Antlion - see https://en.wikipedia.org/wiki/Antlion, possibly Myrmeleon alternans - see https://www.gbif.org/species/2100603. Only two species have been recorded in the UK both rare. Antlions are typical of warmer climes. Larvae excavate pits in loose sand and wait at the bottom for prey to fall into their open jaws.
