from Toll (1962a)

case

The young larvae feed on the developing receptacles of Lamiaceae, and use them also to make their first case. Already before hibernation they switch to mining grass blades. The case then is a laterally compressed leaf case of 13-17 mm with a mouth angle of c. 30°. The colour initially is yellowish white but quickly turns brownish.

As hostplant of the young larva generally Lamium and Salvia are mentioned; however, Baldizzone (2004a) only cites Thymus.

hostplants, as leafminer

Poaceae, oligophagous

Alopecurus; Anthoxanthum; Avena; Briza; Bromus; Dactylis glomerata; Holcus; Koeleria; Poa.

Suire (1961a) mentions Holcus as the main hostplant.

phenology

Larvae from October till May (Hering, 1957a).

BENELUX

BE recorded (Phegea, 2009).

NE not recorded (Fauna Europaea, 2009).

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

From Germany and Poland to the Pyrenees, Italy, and Greece, and from France to Romania; disjunct also in North Russia, Estonia, and South Russia (Fauna Europaea, 2009).

larva

Closely similar to the larva of C. lixella (Suire, 1961a).

notes

Sich (1921b) gives an extremely detailed description of the biology of the larve while it is born and lives in the flower (Salvia pratensis, in this case).
