While walking past a field, I noticed a pair of Monarch butterflies mating. They clung to the seed-filled head of Queen Anne’s lace as it bent over in the breeze. The last generation of the season will make the long migration south to over winter in Mexico. The Monarch’s numbers have increased slightly, but the overall population has sharply decreased since the 1990’s. The Monarch Butterfly has not been assessed by the IUCN. Taken near Katama, Edgartown, Massachusetts, USA.
