Identification
Distinguished from by combination of blue upper wing coloration, medium wingspan (64–76 mm), and distribution. Similar in Myscelia may overlap in range; precise identification requires examination of wing pattern details and geographic context. Strays in Texas are distinguished from resident Nymphalidae by the distinctive blue wing coloration.
