Sitting for ages in a small patch of grass on the sea wall, to identify the maker of a persistant nocturnal sound. Patience was rewarded when this exotic looking character hove into view. Apparently, the rate by which the males rub their wings together, to generate their particular free wheeling sound, is determined by temperature. I consider the feasibility of a cricket thermometer.
