A very rare species in Belgium, more recorded in the north of the country. Possibly overlooked as larval feeding signs can be found quite easily.
The larva bores and feeds in apples and plums. One or often two holes are visible in the fruit where brown frass is ejected. Sometimes a short dark mine can be seen underneath the fruit skin. From July onwards (at least on apple) the larva creates several superficial lines on the epidermis that radiate from the central hole. These traces remain on the apple untill autumn and can easlily be used to confirm the presence of the species. Hibernation and pupation takes place in a cocoon elsewhere, often under loose bark.
The adults fly from mid May till the end of June. They come to light. A specific pheromone is available for this species.
Orchards, gardens and other habitats where the host plants occur.
