An influx of Clouded Yellow Butterflies (Colias croceus) has reached Sweden. A pea-field outside Flen saw a surprising hatch last week, with 50+ butterflies of this rare species so far north.
The fact that some collectors actually caught and killed more than 30 (!)of them the first day has braught lot of controversy. Now only a few specimen seem to remain.
