As you may know, the Powdered Brimstone was originally included on our poster of the butterflies of Corfu because early indications were that it was probably a resident species on the island. See the following link for more information on this story:

Powdered Brimstone species information

Furthermore, Corfu is situated very close to the known distribution of this eastern European species.

However, after looking for this species for the last 10 years, with no definite identification coming forward, Corfu Butterfly Conservation has provisionally placed the Powdered Brimstone on to the unconfirmed list.

If you think you have seen this species (or any other species that we do not have on our confirmed list) you can still report your sightings by contacting our CBC verifications officer at:https://corfubutterflyconservation.org/contact.php

One last point, it is far easier to identify male Powdered Brimstones than females.
