Arizona Moth - Prorella mellisa

Arizona Moth - Prorella mellisa
Twilight Road on Mt. Graham near 7500 foot, Graham County, Arizona, USA
September 14, 2017
Added here at least tentatively - seems to match best with J. Vargo MPG image, and supported by BOLD images and Ferris p. 139 March 15 2018 Lepidoptera of North America 14. Geometroidea: Geometridae: Larentiinae: Eupitheciini (Part). Ranges to Arizona. One feature that stands out is the sharper pair of featherlike markings at FW apex from other Prorella. Note that Ferris spells it "melissa".
