Nice find! Actually, I think this is the Columbia Silk Moth (Hyalophora columbia) rather than the Polyphemus.
hi Denis a columbia silk moth it is thank you a lot
very nice Martin thank you for sharing
If I would put all my moth-butterflies -beetles photos on BNB that would be about 1400 + that from NB
I got 1200 + moth/butterflies just for Pbase
Beautiful, Tom! I've not seen this one yet.
Nice find Tom ! My fave native Saturnnid !
