Incurvaria masculella: excision on Vaccinium myrtillus

another leaf

mine

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.

hostplants

Polypfagous on woody plants.

Carpinus betulus; Castanea sativa; Corylus avellana; Crataegus; Fagus sylvatica; Quercus rubra; Rosa; Tilia cordata, platyphyllos; Vaccinium myrtillus.

In Britain Hawthorn is the main hostplant (Heath & Pelham-Clinton, 1983a), quite unlike the situation in continental Europe.

Mining larvae in May – June (Heath & Pelham-Clinton, 1983a).
