Phyllonorycter klimeschiella (Deschka, 1970)
Arbutus canariensis, Teneriffa; from Klimesch (1979a)
Initially a lower-surface epidermal corridor along the midrib. This makes place for a tentiform mine of 32-40 x 8-9 mm, with one Y-shaped fold. Frass mostly scattered throughout the mine, less often in a clump. The roof of the mine is completely eaten out, no green centre is remaining. Pupation within the mine, usually in its top part, in a cocoon of 5.5 x 1.5 mm, covered with frass. The mine is vacated through the underside.
Preference for young shrubs.
Occupied mines found in January – March.
