Coleophora alnifoliae Barasch, 1934 [Lepidoptera: Coleophoridae] Coleophora alnifoliae Barasch, 1934. Dtsch. ent. Ztg.: 36.

Leaf-mine: The larva creates a succession of cases, in this instance fashioned from parts of a leaf. The final case is 11-13mm long, slender, and fixed at 45° to the leaf surface, with anal end laterally compressed and bivalved (British leafminers). The species overwinters in one of these cases, in some populations twice before emerging as an adult (UKMoths). Larva: The larva is illustrated in Nederlandse bladmineerders. The case is illustrated in UKMoths, British leafminers and Nederlandse bladmineerders Pupa: Details unknown. Hosts in Britain: Betulaceae       Alnus     Plant, in Pitkin & Plant, 2005 Alnus     UKMoths Alnus glutinosa Alder British leafminers Hosts elsewhere: Betulaceae       Alnus glutinosa Alder Nederlandse bladmineerders Alnus incana Grey Alder Nederlandse bladmineerders Time of year - mines: Probably from September (early feeding not recorded) to November, feeding again from late May to June or July. There is also a biennial population, which aestivates and completes feeding in June or July of the second year (British leafminers). Time of year - adults: Mainly in July and August. Some populations only produce adults every two years (UKMoths). Distribution in Britain: A rather local species which is slowly increasing its range. It occurs in scattered colonies in central and southern England, but also occasionally elsewhere (UKMoths) including East Kent, Hereford, West Gloucester and Worcester (NBN Gateway distribution map - JNCC and NE). Distribution elsewhere: Widespread in Europe including Austria, Belgium, Czech Republic, Danish mainland, Estonia, Finland, French mainland, Italian mainland, Latvia, Lithuania, Norwegian mainland, Poland, Romania, Sardinia, Slovakia, Slovenia, Swede, Switzerland and The Netherlnds (Karsholt & van Nieukerken in Fauna Europaea). Parasitoids: Unknown.
