Behavior
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.
Predators
The Ichneumon wasp ''Dirophanes invisor'' is a parasitoid which specializes on ''T. viridana''.References:
