Mothra

this fella, or gal, was so nice to let me take a closeup from inside while he was outside.
and then even nicer to allow me to get quite close for an outside shot of its other side. i looked at bug guide and found a silhouette that seemed right, but no match in their list of geometridae. i tried moths of north america, and the subset there of moths of wa state. i couldn't find anything close. it is, to me anyway, a rather distinctive sort of wing pattern.

i like its appearance, and the quality of the photos, so i'll show them to you. i wanted to id this moth because i am curious about it. what does it eat? how long does it live? i like hearing the latin nomenclature, but i enjoy it as a way to know about the subject.
