The attractive, easily identified and day-flying butterflies have received a lot of attention and the list will probably never by increased (unless a rare migrant Clouded Yellow passes through!)
The moths (some of which are day-flyers too) have been studied to a reasonable extent with a moth trap run there on several occasions.
The Large Skipper is a bright amber-coloured butterfly that depends on grasslands. It occurs at Keyworth Meadow and was chosen as the emblem for the reserve. During May, a small day-flying moth, the Chimney Sweeper, can be found fluttering around its host plant, Pignut.
