Rosemary Beetle

Chrysolina americana can reach a length of 5–8 millimetres (0.20–0.31 in). They have a colourful elytra with metallic green and purple longitudinal stripes. The wings are quite short, so these beetles can not fly.

This species feeds on various aromatic Lamiaceae, mainly on rosemary (Rosmarinus officinalis) (hence the common name), lavender (Lavandula) and thyme (Thymus).
