Classification:
Chrysolina fastuosa belongs to the subfamily Chrysomelinae, tribe Doryphorini.
Distribution:
Widespread in Europe.
Habitat:
Forest edges, roadsides, ruderal areas and extensive grassland.
Description:
Length 5 - 6 mm; upper side gold-green glossy; elytra mostly with variable blue or reddish longitudinal stripes; oval eyes; claw tarsomer of front tarsi below with a strong tooth.
Biology:
The Dead-nettle Leaf Beetle Chrysolina fastuosa forms one generation per year.
The oligophagous species lives on labiates (Lamiaceae) of the genus hemp-nettle (Galeopsis), as well as on some species of deadnettle (Lamium). The imagines appearing in spring first feed on white deadnettle (Lamium album) and then change to the later germinating hemp-nettle. The pale yellow eggs are deposited in the calyxes on the young seeds from June to July. After hatching, the larvae initially eat the seeds and calyxes at night, later they also feed on the underside of leaves. During the day they hide in the seed capsules. In September, after the end of the feeding phase, the larvae are fully developed and go several centimetres deep into the ground to pupate.
About hibernation of Chrysolina fastuosa different data are available. These include hibernation as larva (pre-pupa) or pupa and also as imago.
