of the Lepidoptera of Belgium

Incurvaria masculella ([Denis & Schiffermüller], 1775)

A common species throughout Belgium.

The young larva makes a circular blotch mine in the leaves of Crataegus or Rosa, sometimes on other trees or shrubs. Then it falls to the ground in a case cut from the blotch. This case is subsequently replaced by a vilvalved one made from two oval pieces of dead leaf. The caterpillar then eats dead leaves. It hibernates fully-fed in that case. Pupation in the case amongst leaf-litter.

The adults fly from late April till the end of May. The moths are active during the day.
