Common in gardens, orchards and hedgerows throughout the British Isles. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 14-22 mm. Dark specimens of
C. splendana are reminiscent of
C. pomonella, but the latter is distinguished by the more pronounced, transverse, dark brown strigulation and the large, distinctly coppery ocellus of the forewing [Bradley]. Larva feeds within fruit of Apple, Quince, Pear, Plum, Walnut and Whitebeam, causing sufficient damage to be a serious pest in some areas, over-wintering in a cocoon.
