The Numbers of some Ladybug species have been rapidly declining since the 1990s, Each adult Ladybug is 6 - 8mm long and is easily identified by the seven black spots on the elytra (wing cases) and the white patches on the sides of its head. The eggs are laid in batches of 10 - 50 in aphid colonies and the larvae can eat scores of aphids each day. Ladybugs hibernate during the winter in colonies of up to several thousand adults, often in houses and garden sheds, where they should be left undisturbed, if possible.
