Coleophora trigeminella

Coleophora trigeminella is a moth of the Coleophoridae family. It is found in most of Europe, except Ireland, the Balkan Peninsula and the Mediterranean islands.

The larvae feed on Amelanchier ovalis, Cotoneaster, Crataegus laevigata, Crataegus monogyna, Malus sylvestris, Prunus avium, Prunus spinosa, Sorbus aria and Sorbus aucuparia. They create a reddish-brown, tubular silken case of 5–6 mm. The case is weakly constricted near the anal end, and strongly just behind the mouth. The mouth angle is 0°. Normally, the fully developed case is trivalved. The larvae are found on the underside of the leaf. Fully developed cases can be found in late April and early May.
