Hello all,

I found that Catocala in Quebec, Canada (near Vermont) September 2nd 2011.

Is it possible to identify the Catacola species???

Thanks alot for your appreciated help

I'd probably go with Catocala neogama (J.E.Smith, 1797).

Thanks for your help honeym...

I am hesitating between Catocala neogama and Catocala subnata... :-/

Any comments?

Thanks again for your so appreciated help

The two are very similar and, without seeing the hidwing (which has additional characters), I felt more comfortable with the forewing markings being those of C. neogama.
You could always try asking the CNC.
Best wishes

Sorry, I thought you might have known.
It's the Canadian National Collection:

The lepidopterist there is now Chris Schmidt. He may be able to help.

These two species are extremely similar and there is no way to be certain. There are plenty of photos that are "mislabelled". People interpret differences based on these labelled images, many of which may not be under the right heading. So right now, they are best identified by specimen analysis.
