Apparently, the Red Admirals are arriving in North America in record numbers. The butterflies are on their way north, up as far as Ontario, after wintering in Guatemala.
When a species’ local population suddenly increases in size, the phenomena is called an irruption.
The Red Admirals (Vanessa atalanta) usually begin to migrate in March and arrive in May. But this migration is four to five weeks early.
I saw a Red Admiral, Sunday at Whole Foods Market. And again in my garden. And again just running errands.
The irruption was first brought to my attention by Scott on his blog “Little Crum Creek“.
Read more on the current irruption on “The Daily News Online” and on the Plain Dealer.
There is also a Red Admiral Research site at Iowa State University. But the scientists are outdoing research and haven’t updated the site yet.
