When experts differ

This is a butterfly that I photographed Oct. 20, 2020 in our Wildscape. It is in the metalmark family of Riodinidae. On that, the experts agree. 

Here's where they differ: On iNaturalist, my observation was identified as a Rawson's metalmark (Calephelis rawsoni). A few days ago, I received an email from Butterflies and Moths of North America, confirming that my sighting is a fatal metalmark (Calephelis nemesis). 

Stay tuned.
