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

Leaf-miner and case-bearer: The larva creates a succession of cases, in this instance fashioned from parts of a leaf. The final case is 11-13 mm long, slender, and fixed at 45° to the leaf surface, with anal end laterally compressed and bivalved (British leafminers). A slender, brown, spathulate leaf case, in the end about 13 mm long; mouth angle about 15°. Young case slender, not hooked (Bladmineerders van Europa). Case of Coleophora alnifoliae on Alnus glutinosa Image: Willem Ellis (Bladmineerders van Europa) Larva: The larva is described and illustrated in Bladmineerders van Europa. The case is described and illustrated in UKMoths, British leafminers and Bladmineerders van Europa. Pupa: Details unknown. Adult: The adult is illustrated in UKMoths. The male genitalia, but not the femaile genitalia (check for update), are illustrated by the Lepidoptera Dissection Group. Hosts in Britain: Betulaceae       Alnus     Pitkin & Plant Alnus     UKMoths Alnus glutinosa Alder British leafminers Hosts elsewhere: Betulaceae       Alnus glutinosa Alder Belgian Lepidoptera Alnus glutinosa Alder Bladmineerders van Europa Alnus incana Grey Alder Belgian Lepidoptera Alnus incana Grey Alder Bladmineerders van Europa Alnus viridis   Bladmineerders van Europa Betula     Bladmineerders van Europa Time of year - larvae: 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). The species overwinters in a cases, in some populations twice before emerging as an adult (UKMoths). Time of year - adults: Mainly in July and August. Some populations only produce adults every two years (UKMoths). Distribution in Great Britain & Ireland: 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). NBN Grid map: 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 Netherlands (Karsholt & van Nieukerken in Fauna Europaea). NBN interactive distribution maps of known host species in Britain and elsewhere: Alnus glutinosa, Alnus incana, Alnus viridis Parasitoids in Britain and elsewhere: Unknown.
