Description, Biology, Life Cycle, Damage, Common Names, Images

- Adult: 16 to 22 mm wingspan. Ochrous to yellow leathery fore wings with median and darker apical spots. Dark grey hind wings (*) .
- Eggs: egg-masses of a greenish yellow colour, laid indiscriminatly on either side of the leaf.
- Larva: translucient steely blue green colour with more or less developed brown spots. Prothoracic plate same colour as the body and sometimese spotted with brown in its posterior half (*) .

- Host plants: fruit trees, particularly apple and pear.
- The hibernating caterpillar resumes its activity in March-April. Essentially leaf-eating, it maintains itself in shelters consisting of leaves bound together by silken threads. It can also nibble at the skin of fruit near the foliage.

[R]Life Cycle
- 2 generations a year.
- Overwintering takes place in the larval stage, in silken cocoons. This tortrix has three periods of larval activity: in spring at the time of the regaining of activity, in summer and in autumn. The adults arising from the winter generation of larvae fly in June-July, those of the 2nd generation in August-September. The larvae are active until the end of September, then they hibernate.

Present as a sporadic pest in orchards, this tortrix causes damage to leaves (*) and to fruits which are in contact with the leaves.
