A small genus confined to Europe. The position assumed 

 in repose by the imago is that of ZeUeria, and in this instance 

 there can be little doubt that it assists (in con j miction with 

 the colouring) in producing a protective resemblance to the 

 droppings of birds. Imago with forewings elongate. Larva 

 certainly often very variable and assuming different forms 

 locally, beneath a slight web on upper surface of leaves. Pupa 

 in dense white cocoon.
