[R]Description
- Adult: 14 to 17 mm wingspan. Dark grey head and thorax shiny. Fore wings with the basal and anal thirds slate grey, the centre being occupied by a creamy white band sprinkled with a few black spots. Slate grey hind wings (*) .
- Eggs: oval and 0,75 mm long, they are deposited in small clusters on the shoots and leaves.
- Larva: 11 to 13 mm, narrow, black head and thoracic plate, light brown body (*) .

[R]Biology
- Host plants: apple, pear, rose (Rosa) and sometimes sorbus (Sorbus).
- Egg: embryonic development lasts 7 to 11 days.
- Larva: The caterpillars gnaw the buds (*) then the leaf parenchyma, principally its lower surface. Larval development of first generation is completed 3 weeks after activity resumes.
- The pupation takes place in the rolled up leaves and lasts 2 to 3 weeks.

[R]Life Cycle
- 1 to 2 generations per year.
- The larvae hibernate in small brownish cocoons made in the bud axils; they resume their activity when the buds split open.
- The moths appear from mid-June to mid-July. Some larvae grow rapidly and pupate to produce a second generation of adults during the summer; the others develop slowly and build a hibernaculum in September-October.

[R]Damage
The damage caused to apple (*) and pear buds can reduce cropping considerably. In the case of rose, damage occurs only on flower buds.
