This tiny sun moth was seen on Hairy Four O'clock (Mirabilis hirsuta) at ~7:15 pm in the CO foothills at ~ 6400' elevation. We will also post an image of two dimorphic adults and of a mating pair.
They seem to be Neoheliodines nyctaginella with the black edging on the posterior margin of the forewing from wing base to first dorsal metallic spot, which is diagnostic for Neoheliodines nyctaginella.
