Hi,

At beginning of july i have been up in Retezat National Park. In a lot of places i have found galls (rolled leaf) on Dryopteris filix-mas.
From what i have read he causer is an anthomiid Chirosia betuleti.

Are also other species associated with this fern? I ask this because from what i seen on Fauna Europaea is not present in Romania (the closest country in which is signaled is Slovakia) ( http://www.faunae...on1=129180 ).

If is this species and not yet signaled will be good o have some adults i think, how to proceed for this?

Thanks for the help,
cosmln
