- Host plants: stone-fruit trees, particularly peach, as well as apricot, plum, almond, and cherry.
- Adult: The female lays her eggs singly at the base of the leaves.
- Egg: development lasts 12 to 15 days.
- Larva: The caterpillar forms galleries in the young shoots and can attack 5 to 6 branches (*) ; it also penetrates the fruit, forms galleries in the pulp and then gnaws the stone.
- Pupa (*) : pupal stages lasts 10 days.
- 2 annual generations.
- the caterpillars having hibernated, abandon their shelter at the time when the first leaves appear and penetrate the branches, then, their growth finished, they pupate. The adults lay eggs and after hatching, from July to the end of September, the neonate caterpillars penetrate the shoots and especially the fruit, then pupate in a leaf or at the base of the fruit. Egg laying occurs on leaves and the young first-instar caterpillars shelter under the bark of the new years shoots to hibernate.
The attacks on shoots are not very damaging except in nurseries. However, late fruits can be damaged significantly.
