Gypsonoma oppressana

Gypsonoma oppressana, commonly known as the poplar bud-worm, is a moth belonging to the Tortricidae family. It is found on Madeira and in central and southern Europe, from Transcaucasia to Kazakhstan and Tajikistan.

The wingspan is 12–15 mm. Adults are on wing in June and July.

The larvae feed on Populus nigra, Populus alba, and Populus tremula. They are seen as a minor pest to these trees. Initially, young larvae consume the surface of the leaf from the underside, aligning themselves at an angle to the veins and residing beneath a silken web. As they mature, they transition to feeding inside the buds, migrating from one bud to another.
