摘要：

Cannibalism of eggs by larvae of Adalia bipunctata, an aphidophagous species of ladybirds, is important for survival when aphids are scarce. Ladybirds survive longer by eating eggs of their own species rather than aphids. Since it costs less, in terms of larval growth, to eat eggs rather than aphids, cannibalism has a strong advantage under conditions of prey scarcity.
