No other book in print covers the British species of the family Pyralidae, which includes such familiar species as the Mother of Pearl, the China-marks and the Grass Moths. All 208 species are clearly described in the text and all are illustrated photographically in the 272 figures on the colour plates, showing sexual dimorphism and different colour forms. The text gives a concise description of each species and its more striking races or forms, aided, where necessary, by line-drawings. Information is included on life histories, habits, seasonal occurrence, geographical distribution and host-plants. There is also a check list of the British Pyralidae.
