case
Reddish brown, tubular silken case of only 5-6 mm. The case is weakly constricted near the anal end, and strongly just behind the mouth. The case is sharply bent there; therefore the mouth angle is 0° and the case lies adpressed to the leaf. The fully developed case normally is trivalved. Larvae at the underside of the leaf.
hostplants
woody Rosaceae, oligophagous
Amelanchier ovalis; Cotoneaster; Crataegus laevigata, monogyna; Malus sylvestris; Prunus avium, spinosa; Sorbus aria, aucuparia.
Sorbus is said to be the main hostplant. A case of xenophyagy on Fraxinus excelsior has been described (Emmet ao, 1996a).
