Male
He is very pale whitish-yellow and without any discal spots. This is more likely a male Straw Besma, Besma endropiaria. Let's double check this, before placing him.

Besma
Thanks Bob. I have not seen any images of Besma endropiaria with this otherwise unusual x-shape in the PM line. My models were and ; however, I agree the color is a bit off and the wings are not as pointed at the centers as most B. quercivoraria. Fortunately I collected this one and hope to get a definitive ID.
