Archips podana Scopoli Fruit tree tortrix moth

This is one of the most abundant tortricid species to occur on fruit crops. The larvae damage the buds, leaves and developing fruits of apple, pear, plum, currant, raspberry and many other plants.

BIOLOGY

Adults are usually most abundant in July. They deposit eggs in flat, green batches on the leaves of various trees. The eggs hatch about 3 weeks later and the larvae then feed beneath silken webs often formed between leaves and adjacent maturing fruits. Larvae eventually hibernate, usually in their third instar; under favourable conditions, however, some may complete their development in the summer to produce a partial second generation in the autumn. In early spring, overwintered larvae, including those from any second generation, again become active; they attack buds and young leaves. Most larvae are fully grown in late May or June. They then pupate in spun leaves and adults emerge several weeks later.
