Fatal Metalmark Calephelis nemesis

Southwestern and one of several look-alikes in Texas. Likely this is the commonest species in most areas. And in Big Bend, where this was taken, it would be tough to find another Metalmark with this appearance. There are several other Metals there that are not in the Calephelis genus.

Interior of the Fatal. All three of the southwestern species can show the band of darkening. I don't believe the pale outer window is as prominent in the Rawson's and Rounded Metalmarks. Less metallic banded inside than the Rounded. Lovely little things.
