Tiger Moth is this Grammia nevadensis? - Apantesis ornata - Male
Beckwourth, CA, Plumas County, California, USA
April 22, 2009
Size: 2.5 to 3.0 cm
I photographed this in our back yard, near Beckwourth, California in Plumas
County. The only distribution map I can find for Grammia nevadensis shows
the closest distribution in Lassen County, and most of Nevada including
Washoe County both of which are close to our location. The color pattern is
similar to other photos I have found, and would like someone to verify my
identification. I photographed two individuals, slightly different intensity of red
on the underwings. I am assuming two different sexes of the same species.

Could likely be G. ornata. T
Could likely be G. ornata. They are flying strong in California now. The difference in hindwing color is simply a variation, the red ones seem to be rarer. If it was flying at night it is a male, females are diurnal.

Returning to this moth...
it has to be Grammia ornata (although a little small at 3cm). Ornata is the only Grammia that flies in the spring in CA and G. nevadensis is a summer to fall flyer.

Thanks for the clarification, Chris!
Do you have a print or Internet source that you could give me which references this helpful data regarding Grammia flight times in CA? Or, is this knowledge that you have managed to pick up from your observations in this area? I'd like to add this information to the Info pages for both species but it would be best if I could reference a source... Thanks!

.
Most of my info comes from the revision of the genus Grammia by Schmidt, 2009. Send me an e-mail and I'll give you (or anyone who wants one) a copy.

Hi Gloria,
I can't ID your moth, but I made some changes to your post. I cropped and rotated this image (for easier pattern comparison) and I unlinked the two images because you mention that they are two separate individuals. One of our moth experts should be able to help you with this. Nice shot.

Tiger Moth
Thanks for the help in IDing my moth photos. I am also an elementary school teacher. I have been trying to ID all plants and animals that we come across on our property as well as at school.
Last year I photographed a gorgeous Redwood Moth in our back yard, and we have lots of other insects that come and go as the seasons change.
Thanks again, Gloria
