Leaf-miner: Upper-surface, transparant blotch that begins at the leaf margin, generally at the underside of the leaf. Oviposition site covered by a shining brown drop of hardened secretion. Frass in grains or thread fragments. Pupa in the mine, not in a cocoon (Bladmineerders van Europa).
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
Striking, because all segments have a large black dorsal spot. The larva is described by Bilandyacute; (1982a, 1993a, 1994a) and Brechtel and Kostenbader (2002a); and illustrated by Niehuis (2004a) (Bladmineerders van Europa).
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
The pupa is illustrated in Bladmineerders van Europa.
