37.027 Coleophora potentillae Elisha, 1885
< back
top surface of leaf


Food Plant: Many rosaceous shrubs and bushes eg Agrimonia (Agrimony), Filpendula ulmaria (Meadowsweet), Fragaria vesca (Wild Strawberry), Geum spp (Avens), Potentilla spp. (Cinquefoils), Rosa spp. (Rose), Rubus sp (brambles). Also found on Crataegus (Hawthorn), Betula (Birch), Prunus spinosa (Blackthorn) and Helianthemum (Rock Rose)

Mine: September - May

Notes: 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. The mines only penetrate one side of the leaf (as shown) whereas C.violacea punctures through the leaf. The mines illustrated are on bramble.
