Chirosia albitarsis (Zetterstedt, 1845)
Oviposition normally on one of the lower secondary pinnulae. The larva enters a vein and from there descends as a borer in the rachis. Often several larvae together. Attacked leaves can be recognised because the leaf is stunted, often remaining partly unfolded. Pupation in the mine or in the ground. See Brown & McGavin (1982a) for details of the biology.
Larvae in May-June (Hering, 1957a).
