Dark fruit-tree tortrix

The caterpillar lives inside a rolled-up leaf, and it also turns into a pupa there.

Its caterpillar can grow to about 22 millimetres long.

It has two families of young each year, and the moths fly from late May to the middle of September.

Gardeners count it as a pest, because its caterpillars chew the leaves of fruit trees.

It looks a lot like a close cousin, so it can be hard to tell them apart.
