Coming in to land on New England Aster flowers – the number of Monarch butterflies have been reduced this year – apparently because of weather problems in central Mexico where they over-winter and then prolonged and cold winds from the north in spring that made sure many never made it back north of the Great Lakes. Some got here though and now the return migration has begun.
As you can tell form the name, this attractive butterfly did not evolve on this continent. In fact they appeared first about ten years ago at Mirabel Airport a half hour’s drive north of Montreal (so presumably hitched a ride) and seem to like it hereabouts, First seen our garden three or four years ago and caused much confusion until we found about the above as it doesn’t “quite” match any of the small, blue natives. Doesn’t seem to be causing any trouble.
