It’s September — and that means it’s time to start keeping an eye out for monarch butterflies on their way to Mexico! In recent years, monarchs have come through Connecticut in mid to late September, making a regular stop at Hammonasset State Park. To try to understand why monarch numbers are declining, scientists and citizens are carefully monitoring their numbers and locations as they travel. Get involved by keeping track of their migration at this web site and posting records of any monarchs you spot this fall!
