The larvae of Coccinella septempunctata bruckii Mulsant were reared under four different temperatures with the aphids or the beetle's own eggs as food. Amount of food was measured by the decreased number of prey in a vial, in which a single larva was contained and the food was renewed every day. The feeding behaviour and total time of feeding in a day were observed, and the number of prey fed and duration of larval stages passed as well as the body length attained under different temperatures were also examined. Although the first instar larvae fed on but a Coccinellid egg could not complete the first moult, the larvae ate more than two eggs reached later stages according to the number of prey consumed, and those took 150 to 170 eggs succeeded to pupate. The duration of larval development, in rearing only with Coccinellid eggs, was much more delayed than in the case of rearing with aphids.
