Sub-species:
Nemoria darwiniata darwiniata - (western & southwestern range)

See Also
Nemoria glaucomarginaria has larger white spots on the abdomen, surrounded by a very similar reddish color and no discal spots on the wings.
The only other Emerald moth with reddish discal spots is
Nemoria zelotes, which has a prominent red terminal line on all wings, and is apparently restricted to Arizona.
