On the Seasonal Migrations of Dione Vanillæ in Kansas.

Abstract

Dione vanillae is a common butterfly in South and Central America, in Mexico, and in the southern part of the United States, from southern Virginia southward to Arizona and California.[1][1] Scudder[2][2] reported it as rare north of the 35th parallel, but I have collected hundreds of specimens in Kansas, and in the Ozark Mountains of Missouri and Arkansas. A few strays have been taken in West Virginia,[3][3] New Jersey and Pennsylvania,[4][4] but Vanillae is really a tropical butterfly. In the central states the northern limit of its usual range falls somewhere in central or northern Kansas; it is fairly common in the southern portion of the state, but is rarely taken more than 150 miles north of the Oklahoma border.
