Some ladybirds often found in gardens
Harlequin ladybird, Harmonia axyridis. A non-native species that became established in Britain in 2004, it is now one of the most commonly seen ladybirds. Adults are 8-10mm in length, and very variable in colour and markings, two common forms are black with two red spots or orange with 18 black spots. Larvae reach up to about 10mm in length and are characterised by having two orange stripes and being spikey. This species feeds on aphids and other insects, occasionally becoming cannibalistic. There is some evidence that it has caused declines in some native ladybirds due competition for food. It is however, not desirable nor necessary to attempt to control this insect, it is easily confused with some native species and is largely a predator of aphids.
Two spot ladybird, Adalia 2-punctata. Adults are 4-5 mm in length and very variable in colour, common colour forms include red with two back spots and black with two red spots. The larva is dark grey with some orange markings. This species is widespread and often found in gardens feeding on aphids. It is sometimes available from biological control suppliers.
