Extremely early map butterfly
It is tempting to ascribe this to the very mild winter but this is different. The butterfly was found indoors and did not emerged in “natural” conditions . Most likely, the pupa was stuck to the Christmas tree which Marcel had in his living room. A few weeks of high temperatures confused the butterfly, making it metamorphose indoors. [Marcel] recorded this on Waarneming.nl accompanied by a photo of the new-born butterfly.
