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, an area I'm eager to begin exploring. 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. With good photos, I hope to illustrate any differences between these and californica; that's one of my reasons for having this website.
