The two spotted ladybird; Adalia bipunctata is a native ladybird to the United Kingdom and Europe although sadly in decline. The adults feed on many species of aphids and are certainly a gardeners friend! During the winter months they will hibernate in window frames, walls, log piles or trees. In the spring they emerge, mate and lay eggs. Each adult can lay about 20-50 eggs per day. The eggs are elongated and orange to yellow colour. Once these hatch they develop into ladybird larvae, which also consume large numbers of aphids before they pupate and become adults. Ladybird adults are highly effective predators of aphids.
Although they can be released outdoors on to infested plants such as roses, they perform particularly well in a confined space like a greenhouse or polythene tunnel.
