Coleophora potentillae

Prunus spinosa, Belgium, prov. West Flanders; © Chris Snyers: Two generations! The mines, of which the lower epidermis has been cut away, are the work of a full grown larva. The case is a youth case, quite different from the full grown case, consisting of many small rings, and having a mouth angle of about 90°.

case

Generally off-white, sometimes darker lobe cae, that lies almost flat on the leaf (mouth angle 30°-50°). Case not remarkably wide in its middle section. The lobes are cut from lower epidermis; as a result the mines can have both the usual small holes, and much larger holes, in their underside. (Compare with C. violacea, that cuts the lobes from the upperside of the leaf.)

hostplants

mainly oligophagus on herbaceous Rosaceae

Agrimonia; Alchemilla xanthochlora; Betula; Crataegus monogyna; Filipendula ulmaria; Fragaria vesca; Geum; Helianthemum nummularium; Malus sylvestris; Potentilla; Prunus; Ribes; Rosa; Rubus; Salix cinerea; Sanguisorba; Spiraea.

How this appareny polyphagy should be uderstood is not clear. Coleophora-larvae are quite agile, and can easily stray, possibly temporarily, onto a wrong hostplant. Also confusion with Coleophora violacea cannot be excluded.
