There are three different species in the genus Adscita that occur in Romania: Adscita statices, Adscita geryon and Adscita mannii.
These three species are very difficult (if not impossible) to distinguish from a photo.
They all are day flying moths with a slow fluttering flight. They generally have a metallic green (sometimes blue) sheen.
