Incurvaria masculella (Denis & Schiffermüller, 1775)
Vaccinium myrtillus, Belgium, prov. Limbourg, de Hoefaert-Lanaken © Carina Van Steenwinkel
Oviposition is by way of an ovipositor, therefore no egg shell visible. The larva makes a small, roundish, blotch; often several in a leaf. Already after its first moult it makes an excision out of the mine, in size almost equal to the blotch (3-4 mm). Thus sandwiched it drops to the ground and continues feeding on dead leaf material.
Polyphagous on woody plants.
In Britain Hawthorn is the main host plant (Heath & Pelham-Clinton, 1983a), quite unlike the situation in continental Europe. Kovács & Kovács (2000a) mention a long series of localities in Romania, exclusively from Quercus.

Mining Incurvaria-larvae, while resting, take a horse-shoe like posture, unlike the larvae of Antispila species.
Described by Patočka & Turčáni (2005a).
Incurvaria muscalella (Fabricius, 1787).
Ruben Meert observed oviposition (in nature) on Malus domestica and Prunus spinosa; at the spot of the egg a tiny bulge could bee seen. This underlines the polyphagy of this species. (Belgium, East Flanders, Lebbeke, 22.ivi.2022)
