Coleophora trigeminella case

from Toll (1962a)


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. perhaps more often on the buds.

host plants

woody Rosaceae, oligophagous

Amelanchier ovalis; Cotoneaster; Crataegus laevigata, monogyna; Malus sylvestris; Prunus avium, spinosa; Sorbus aria, aucuparia. torminalis.

Sorbus is said to be the main host plant. A case of xenophagy on Fraxinus excelsior has been described (Emmet ao, 1996a).


Fully developed cases in late April, early May (Emmet ao, 1996a).


BE recorded (Baugnée, 2011a).
