Rothschildia lebeau forbesi

I believe bayucca is right on.

Usually you can't separate the different Rothschildia from a picture. In this case the geographical range is so close, that an ID is possible. But if you look at the different species from Central- and South America it is very difficult. There are some with special "features" which might be helpful for getting closer, but the rest of them look all almost the same.

the patterns of the Rothschild Moth and the Forbes' Silkmoth are the same but the way they are shaped are a bit different, i think it's a Forbes' Silkmoth

You're right bayucca, my bad on suggesting that species, but they do look very similar.

Rothschildia maurus is a South American species and not found in Texas. There are not much possibilities about this one. There are some rare records on intruders from Mexico like R. cincta. The only "common" one is Rothschildia lebeau forbesi, also called Rothschildia forbesi, but it is actually a subspecies of Lebeau.

Great spotting! I would love to see this in the wild.

Very nice!
