In 2003 and 2004, severe defoliation brought a lot of focus on Winter Moth (Operophtera brumata), Northern Winter Moth (Operophtera fagata), Mottled Umber Moth (Erannis defoliaria), Gypsy Moth (Lymantria dispar) and many other species in eastern Austria, but the general knowledge surrounding other associated feeding larvae proved to be, on occasions, inadequate. An attempt in 2005 using a spanned 3 x 5 m tarpaulin between posts as a caterpillar trap, under four tree species - Ash (Fraxinus excelsior), Hornbeam (Carpinus betulus), Norway Maple (Acer platanoides) and Turkish Oak (Quercus cerris) -, was carried out to bring us in direct contact with tree specific species, with two main objectives: First, increase our practical identification knowledge, and second, get an overview of species found within the different trees and any overlap between species. This proved a successful exercise, and brought some very unexpected results.
