Milbert’s Tortoiseshell, Aglais milberti <LEP124>

Tortoisshells have decidedly different upper and lower surfaces. Milbert’s above is chocolate brown with a two-toned band-- yellow inside, orange outer-- orange basal spots, and blue dots in the dark margin. Below there is no such fire-rim pattern, just a dark brown basal half, tan band, and dark border. Thus it blends exactly into tree bark. It is widespread in North America, here shown on western sneezeweed.
