Symptoms

In the spring, you will notice leaves that are bound lightly together with silk threads and are being eaten. This becomes particularly noticeable in mid-summer when it is too late to treat the problem. Blossom and developing fruitlets can also be damaged. Prevention is possible in early winter and spring.

Spot them

Wingless moths emerge from the soil from November to January and crawl up trunks to lay eggs on the branches. The eggs hatch into pale green caterpillars when buds begin to burst and the caterpillars feed until early June, when they return to the soil to pupate.
