Coryphista meadii

Observation date: June 05, 2022
Submitted by: robpendergast
Specimen type: Photograph
Observation notes: Kind of off-topic - Are there any good references for separating C. biundata and guttivitta? I’ve had a number of Cecrita recently and am having a bit of a hard time finding anything informative on parsing the two species. I tried checking the references BG supplied, but I couldn’t find the article it referred to on the species page.

Coordinator notes: No guides come to mind at present. What I found helps is to copy several clear photos of each of those moths from BugGuide and then compare the photos to note the differences.
