4 Greta oto (Ithomiidae) from Costa Rica feeding on an artificial flower. I love this cute Glasswing butterfly! See the caterpillar here: [link] Naturospace, Butterfly House in Honfleur (Normandy, France), 15/03/2008.
Well, they survive here and in England too, but of course they are bred in large greenhouses where the tropical climate has been artificially re-created. Do you really think it should not be possible to do that in Finland?
Yes in greenhouses they do survive, if i remember right here is one butterfly-house in finland. But still, at south of finland we have got some rare butterflies more common last years, maybe because all that "global warming" or dunno why. Maybe we'll see some new too in the future.
