black flies in Norway May 9, 2015 12:09:37 GMT via mobile Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by blackfly100 on May 9, 2015 12:09:37 GMT I would like to know when the black fly season is in northern Norway, and also elsewhere in Norway. I will be in the coastal north May 29-June 5, then inland southern areas until late June.
