Using a photo for identifying a moth

Dark moths can drive you nuts. Getting a clear photo can be difficult because the critter lacks contrast. A digital photo editor that lets you increase the brightness can help.


Here are two versions of a single image. The one on the left is the original. The moth was sitting on one of the light sockets for a quad of CFL black lights. In order to ID the moth, I brightened the right-hand image to show the ante-median, median, post-median, and sub-terminal lines plus the orbital and reniform spots. The moth was new to me but also quite common: Peridroma saucia, Variegated Cutworm Moth.

Tweaking images is a useful skill. Try it yourself.
