Thank You
There is a lot of sycamore in this area.

Are you sure about this, it i
Are you sure about this, it is more likely A. furcatana.

 
What is it?
What is it that you see that makes it look more like A. furcatana?

 
I've been looking at a lot of
I've been looking at a lot of specimens of this pair and they are not as clear-cut as I'd like. Basically reared specimens are the best way to determine what species it is. So if you have sycamore (Platanus spp.) there, it should be A. furcatana and if you have Manitoba Maple (A. negundo) it should be A. negundana. Of course these host plants broadly overlap in range so it is often a tough call. I so far have not found consistent differences in the genitalia of these two, despite what Freeman 1965 says. What does hold up though is the specimens with the broadest median bands and fewest strigulations are A. negundana and the converse make them A. furcatana. Intermediate individuals are tough to call and yours is one of those, though I lean towards A. furcatana because of the heavy strigulations.
