We are working on a dataset of butterflies in a farmland in Poland. Despite of some efforts we were not able to find a complete list of species (available online) with their ecological/functional attributes which could be useful for Poland (Central Europe). I know that it has been published in a book "Schmetterlinge: Die Tagfalter Deutschlands" and it could be useful for us. Is there any other publication available online, which includes the information we are looking for?
