20. Datiais archippus. — Milk-weed Butterfly, Adams, Brown, 
Dawes, Dodge, Nemaha, Sheridan, and other counties. This well- 
known butterfly appears by the middle or sometimes the first of April, 
and remains till cold weather. It undoubtedly hibernates, although 
we have not found it in winter. At least three points favor this con- 
clusion ; firstly, its remaining so very late in the fall j secondly, its ap- 
pearing very early in the spring ; thirdly, the early species invariably 
have the appearance of old and w^orn specimens, being decidedly faded 
in color.
