THE function of food reserves during diapause is often discussed, but there are very few reliable data. The mass hibernation of adult Semiadalia wndecimnotata (Schneider) (Coccinellidae) in accessible places allowed us to make analyses throughout the winter. Both sexes arrive at the winter quarters on warm, windless days from the end of July to the end of August, and leave from the end of April to the end of May, according to the temperature.
