Description

Ceratomegilla undecimnotata can reach a length of about 5–7 millimetres (0.20–0.28 in). Body is elongated. Elytra are orange-red, while pronotum is black, sometimes with a small white line at the front edge. Elytra show a central black spot and 10 lateral black spots. There are a total of eleven spots (hence the Latin species name undecimnotata), but some spots sometimes are small and barely visible.

This species can be confused with Coccinella septempunctata, but it is smaller and more oval, the central spot above the pronotum is more triangular than round and there is no white around it.

Adults can be encountered from March through October. They mainly feed on aphids.

Distribution

This quite rare species can be found in central and southern Europe.

Habitat

It occurs in open, sunny environments (sunny forest edges, meadows, herbaceous, and dry grasslands, etc.).
