Adelpha eulalia

Arizona Sister

In DNA studies published in 2008, Adelpha eulalia was discovered to be a full species separate from Adelpha bredowii and what is now Adelpha californica. This butterfly reaches into California in the far eastern reaches of San Bernardino County. According to Ken Davenport's Emmel update, the habitat for eulalia is "higher elevations in the New York, Providence and Granite Mountains where the likely host Quercus chrysolepis Liebm. (Fagaceae) occurs." They are no doubt easier to find in Nevada and Arizona; I've seen them in the mountains near Tucson and Ken lists the Spring Mountains near Las Vegas and the Hualapis near Kingman, Arizona.

This is Adelpha eulalia from Montosa Canyon in the Santa Rita Mountains southeast of Tucson, Arizona. I was thrilled to finally get photos of one in such good shape that would actually pose for me. October 15, 2019.

Ventral of the same one. All butterflies should be so cooperative.
