Maximum Growth
Hello. I am curious. Does anyone know, what is the largest recorded specimen anyone has encountered?

Moved
Moved from Cocytius.

Cocytius antaeus
This to me is C. antaeus. C. duponchel would be much grayer with a bluish tint rather than this flat brown.

Moved-Cocytius sp.
Moved from ID Request.

This could be either Cocytius (Amphonyx) duponchel, or the more common Florida species, C. antaeus.

I will have a look at some specimens today to make a final determination between the two possibilities.

EDIT:
After looking over some specimens in the Cornell University Insect collection, I am leaning more towards the occasional Florida stray, Amphonyx duponchel, though I cannot be positive (but perhaps someone else could have a a differing opinion) as to the identification without seeing the hindwings. So for now, I will leave it only as far as the genus.
