pseudostigma (Tempère, 1982)
[Coleoptera : Curculionidae]
Tachyerges pseudostigma (Tempère,
Full depth corridor, beginning at the base of the midrib and very
roughly following the leaf margin; all the while the corridor widens,
until almost the entire leaf has been mined out. Frass, as coarse
grains or thread fragments, in the centre of the mine. The larva
pupates in the mine, in a globular cocoon made of secretion (Bladmineerders van Europa).
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).
