Coleophora violacea (Ström, 1783) [Lepidoptera: Coleophoridae] Phalaena violacea Ström, 1783. Coleophora hornigi Toll, 1952. Bull. Soc. ent. Mulhouse: 18, fig'd. Coleophora albicornuella Bradley, 1956. Ent. Gaz. 7: 148, fig'd. Coleophora violacea (Ström, 1783).

Leaf-mine: The larva feeds on a wide range of trees, shrubs and herbs, favouring Rosaceae, but not exclusively. The fully developed cased larva may be found active in October and again, after winter diapause, in April. Cases, about 6 mm, of diapausing larvae may be found through winter, fixed to a tree or fence post. The dorsal surface of the case is usually covered in leaf fragments, but they can sometimes be worn off almost smooth. The ventral surface is swollen at the middle and has a keel, which usually bends upwards at the posterior. The cases of C. ahenella (on Rhamnus, Frangula, Viburnum and Cornus) and C. potentillae (case less swollen, keel not bent up, resting position less prone) are very similar (UKMoths). Larva: The larva is illustrated in Nederlandse bladmineerders. Pupa: Details unknown.

Distribution in Britain: A wide variety of habitats throughout Britain (UKMoths) including Banff, Elgin, Hereford, Mid Perth, Mid-west York, North Essex, North Hants, South Aberdeen, West Gloucester and Worcester (NBN Gateway distribution map - BRERC, GiGL, NE and SNH). During the day it may be found resting on vegetation (UKMoths). Distribution elsewhere: Widespread in Europe including Austria, Belgium, Czech Republic, Danish mainland, Estonia, Finland, French mainland, Germany, Greek mainland, Hungary, Italian mainland, Latvia, Lithuania, Norwegian mainland, Poland, Russia - South, Slovakia, Slovenia, Sweden, Switzerland and The Netherlands. Also recorded in Near East and North Africa (Karsholt & van Nieukerken in Fauna Europaea). Parasitoids: Unknown.
