The flat and pinhead sized eggs are oval and translucent when first deposited. Later on they turn white.

The silk cocoon is spun under the bark of the host-tree.


The eggs are laid singly on fruit or on the upper surface of nearby leaves. Young larvae bore into the fruit within 24 hours after hatching and then tunnel towards the core where they feed on the developing seeds of especially Malus and Pyrus trees. The caterpillars hibernate full-grown in a silk cocoon under the bark of the tree-trunk or in leaf litter where the pupation takes place the following spring. A second generation is also not uncommon.
The adult moths become active at dusk and are attracted to light.

Flight periods

The adults fly from mid May till mid August. Those emerging in May sometimes produce a second generation which then flies from August till mid September.
