The earliest butterflies of this species which have 

 not hibernated are found in New England in June

 ther south they winter in the imago state, and make 

 their appearance early in the following year, and have 

 several broods in a season. In New England the 

 progeny of the colonists fly to the southward in the 

 autumn.
