Bug FAQ22-spot Ladybird
Psyllobora vigintiduopunctata · Order: Coleoptera · Family: Coccinellidae
Also called: 22-spot Ladybird Beetle, 22-spotted Lady Beetle, 22-spotted Ladybug
The 22-spot ladybird is a tiny 3 to 5 mm beetle with yellow wing covers marked by 22 black spots and a similarly spotted pronotum. It lives low in grassy and semi-open areas such as meadows, gardens and forest edges, and can be found on low vegetation and young tree branches. Both adults and larvae feed on mildew on plants rather than aphids, and the larvae begin eating the fungus a few hours after hatching.
