Copestylum .... male.
Copestylum .... male.
r-m vein darker and looks thickened compared to other veins makes me think Copestylum anna. I have sent it to Dr. Martin Hauser....

please do not include estimated size... it's so obviously wrong
it can only hurt your chances for an id

thank you
I'll try to do better. I m disappointed to observe that I had named the JPG to mention its half inch length, and I didn't report it that way here. Sorry. Good reminder to be careful.
