Sightings on Atlantic Coast Raise Questions
Notice the three reports of monarchs in Virginia and North Carolina. Did the monarchs overwinter along the Atlantic Coast in places protected from freezing temperatures? Did they migrate up from Florida where monarchs are known to overwinter in large numbers? Did somebody release them at a wedding or other celebration? It does not seem possible that they could have come from Mexico. Look at the migration map and notice the progression from Mexico into Texas and then into nearby states. Where do you think the monarchs came from?
