- Host plants: apple, pear, cherry, plum, quince and peach.
- Adult: nocturnal tendencies; it lives 7 to 10 days. The female lays on the underside of the leaves inserting its eggs in the parenchyma with its oviscapt. The moth from the last generation hibernates, sheltered in cracks of bark or other natural shelters.
- Egg: embryonic development lasts 15 days.
- Larva: the caterpillar forms in the parenchyma a characteristic mine, elongated and narrow (*) ; by the end of its growth, (20 to 25 days), it vacates the gallery, ties the sides of a neighbouring leaf with silk threads and pupates in a cocoon formed by a few threads (*) .
- Pupa: development lasts 15 days.
- 3 to 4 generations per year.
- The adults having hibernated oviposite in April and May. The second flight occurs in June-July and the third begins end of July or in August; sometimes there is a fourth flight from September to November. It is these moths (third generation) which hibernate.
In cases of heavy infestation, the caterpillars which live between the two epidermis of the leaf can cause almost complete defoliation of the trees and reduce cropping and also fruit production potential for the future.
