case

Sheath case. The fully developed case is slender, shining black brown, about 9 mm long. Towards the end a narrow, transparent yellowish ventral keel. Mouth angle 50-60°. Cases at the leaf underside.

host plants

Lamiaceae, oligophagous

Agastache foeniculum; Clinopodium vulgare; Glechoma hederacea; Lycopus europaeus; Melissa officinalis; Melittis melissophyllum; Mentha aquatica, arvensis; Nepeta cataria; Orignanum vulgare; Prunella vulgaris; Salvia pratensis, verbenaca, verticillata; Satureja; Stachys, Thymus.

Michaelis (1983a) doubted the occurrence on Origanum, but the picture above refutes that. Maarten Immerzeel found in his Wageningen garden most cases on Menta, several on Melissa officinalis, two on both Salvia verticillata and Agastache foeniculum, and none on Glechoma or Stachys!

distribution within Europe

notes

In continental Europe the species also lives on Thymus (Patzak, 1974a; Szőcs, 1977a; Razowski, 1990a). Then confusion may arise with the rare C. niveicostella, that is bound to thyme. Its case is indistinguishable from that of C. albitarsella. A differentiating character is that in the larvae of niveicostella the metanotum is concolorous with the remainder of the pale green , while in albitarsella the metanotum bears two black oval sclerites.
