Six-belted Clearwing

This afternoon (19th ) at Crookham/Greenham Common (SU519645) I had 10 Six-belted Clearwings to my API lure.These came within minutes of exposing the lure. Some even allowed themselves to be photographed. I was surprised to see that they varied a lot in size with some individuals being almost twice as big as others. (Once again, Many Thanks to Marc B. and Dave W, for help on this.)
