In early spring 2007 a marked Sympecma paedisca was seen on a reproduction location. The way of marking showed that this indivdual was marked in the fall of 2006 on a well known hibernation spot about 7 km away from the reproduction area. This incidental encounter maybe an indication that some individuals manage to return the long way home to the reproduction area after hibernation.
