De Rouwmantel; een blijvertje?

The invasion of the Camberwell Beauty (Nymphalis antiopa) in 1995 in the Netherlands was an event which will not soon be forgotten. Favourable winds brought large numbers of butterflies from south- eastern Europe and there were high hopes that this rare species would resettle here. The following year butterflies were sighted after hibernation and it is believed these did reproduce, although no caterpillars were actually seen. In 1997 there were only a few sightings of the Camberwell Beauty, making it once again a rare species.
