Enarmonia formosana, the cherrybark tortrix or cherry-bark moth, is a small but colourful moth species of the family Tortricidae found in Asia, Europe, North Africa and North America. It was first described by the Italian physician and naturalist, Giovanni Antonio Scopoli in 1763 and is the type species of its genus (Enarmonia), and by extension of the tribe Enarmoniini of subfamily Olethreutinae.

Descripton

The wingspan is 15–19 mm. The forewings have a moderately arched costa.The ground colour is ferruginous-ochreous, with leaden metallic striae. The costa is blackish, posteriorly strigulated with white. The basal patch has the edge sharply angulated in the middle and indented near dorsum> The central fascia is interrupted in the middle dark fuscous, marked with ferruginous-ochreous. The ocellus is black, edged with leaden-metallic and streaked with ferruginous, surmounted by a dark fuscous curved mark.The hindwings are rather dark fuscous.The larva is rosy - whitish.

The moths fly from May to October in the temperate parts of the range (e.g. Belgium and the Netherlands).

The caterpillars feed on the bark of woody Rosaceae of subfamily Amygdaloideae, namely hawthorns (Crataegus), apples (Malus), cherries (Prunus) and pears (Pyrus). In particular, they have been noted to forage at canker lesions. They prefer mature trees and produce a reddish frass at the entrance to their tunnel. Signs of larval feeding can be seen at cracks in the bark, or at joints with branches. The larva pupates at the entrance to its tunnel, often enclosed by frass secured with silk.

Distribution

It is native to most of Europe, extending eastwards through Asia to Siberia and Kazakhstan and south to Maghreb. in North Africa. Possibly and most likely introduced populations are found in Asia Minor and North America.
