Incurvaria praelatella: larval case

excision, after having been enlarged by a piece of dead leaf mateiral

mine

Small (< 1 cm), full depth blotch, transparant when fresh, starting at the leaf margin, usually near the leaf tip; frass in scattered grains. Sometimes several mines in a leaf. The larva soon makes an elliptic double sided excision. Subsequently, it continues feeding within this case.

host plants

mainly Rosaceae; weakly polyphagous

Achillea; Agrimonia; Alchemilla vulgaris; Filipendula; Fragaria vesca; Geum rivale; Potentilla reptans; Rubus fruticosus; Spiraea douglasii.

Preference for damp, shady situations; Fragaria is the main host plant genus (Hering, 1957a).

phenology

Mining larvae in June – July (Heath & Pelham-Clinton, 1976a), or even later (Emmet, 1974a); I myself found them in mid August. Hering (1957a) writes Augustus – October.

BENELUX

BE recorded (Phegea, 2009).

NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).

distribution within Europe
