ABH: 37.027
BF: 513
Family: Coleophoridae
Taxon: Coleophora potentillae
Authority: Elisha, 1885
Vernacular: Potentilla Case-bearer
Account: Local in rough grassland, damp woodland, fens, ditches and woodland rides in England, south of a line from Lincolnshire to Herefordshire, central and western Scotland, and western Ireland Like many of the Coleophora, imagines are virtually impossible to identify without recourse to dissection, and best identified in the field, where in Hampshire the larvae are mainly found on rosaceous herbs and shrubs. Foodplants are wide ranging, quoted as including Agrimonia (Agrimony), Filpendula ulmaria (Meadowsweet), Fragaria vesca (Wild Strawberry), Geum spp (Avens), Potentilla spp. (Cinquefoils), Rosa spp. (Rose), Rubus sp (brambles). and also Crataegus (Hawthorn), Betula (Birch), Prunus spinosa (Blackthorn) and Helianthemum (Rock Rose). The case resembles that of C.violacea, but does not lie so flat again the leaf as this species (having a mouth angle of 30 to 50°). C.violacea also has a case which bulges in the middle, whereas in C.potentillae the case tapers towards the posterior.
