| Tortrix viridana (L., 1758) |
The tortrix moth Tortrix viridana is known as the European oak leafroller and the green oak moth. It is a distinctive green moth whose larvae feed on tree leaves, especially oak.
An infestation of the larvae can defoliate an oak tree. The adult female lays its eggs next to leaf buds which the larvae consume when they emerge. As the larvae grow bigger they eat larger leaves, and then roll themselves up in a full-sized leaf to pupate.
The Ichneumon wasp Dirophanes invisor is a parasitoid which specializes on T. viridana.
