Leaf-miner: The egg is deposited in the base of the midrib. After oviposition the female severes the petiole, causing the petiole to break. The leaf start to wilt and falls, but still remains green for a considerable time. The larva tunnels in the midrib, and makes from there broad, full deep blotches in the lamina. Frass dispersed in the mine. Often several larvae in a leaf. Pupation in the ground. Blommers & Vaal (2002a) and Gønget (2003a) describe the biology in more detail. (Bladmineerders van Europa).

The mine is also illustrated in British Leafminers.

Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).

Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).

Adult: The adult is illustrated in MacroidID.RU.
