Occurrence
The pine shoot moth lives in young pine forests and is a pest of the Scots pine . The adult flight time is June and July, during warm twilight .
Way of life
The female lays the fertilized eggs one by one on the buds and needle sheaths of the pine, from which the caterpillars hatch at the end of July . First of all, they eat the surrounding needles and then dig into the side shoots where they hibernate . In spring they continue to gnaw towards the more central shoots. In June of the New Year, they pupate within three weeks. The caterpillar of this type of winder is a leaf miner because it hollows out its host plant and does not spin leaves together.
Harmful effect
The pine shoot winder is a forest pest . Its caterpillar eats the needles of the Scots pine, mines the shoot tips and destroys two to three buds per caterpillar during the development period. The dead shoot tip will be replaced by several shoot tips next year.
