C. Propinquilinea
This looks more like 9185 -
Colocasia propinquilinea
. See the difference between the two species in this
MPG plate
.
Flavicornis
is much lighter and less mottled, with distinctive difference in dark forewing band.

Moth ID
Jason...All I can say is that this individual was identified from the specimen by an ackknowledged Noctuid expert. I've been told many, many times that moths are quite variable in their coloration and markings, which is why they HAVE to be identified from the specimen.

Your call
I understand. Although unless the genitalia were dissected and examined under magnification, I would personally disagree with the Noctuid expert. There is certainly great variation in color and pattern intensity among moths, particularly of Noctuids. However, in the Colocasia genus, much like the Catocala genus, there are distinctive markings which are particular to each species despite the variation in color saturation. One of which is the zigzag line coming from the costal margin toward the tip of the forewing. The moth in your photo, without a doubt, bears the zigzag pattern of
propinquilinea
and not
flavicornis
. Close examination of the peaks in the zigzag pattern show this. To my knowledge, over the past 21 years of studying lepidoptera, I've never known this particular marking to vary (not that I've dwelt on Colocasia...lol). However, like I said, if the Noctuid expert performed genitalia dissection and examination, then I concede to his judgment. Hope I didn't ruffle any feathers - just throwing in my thoughts. :)

Thank you for your comments
I know, for a fact, that the most important factor in a moth ID (from the specimen) is examining the genitalia with magnification. Of course, I could do that and still wouldn't have a clue as to what to look for. That's why I send my specimens to an expert.
