Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Observation notes: A rather chewed up and faded individual. Based on slightly curved leading edge, scalloped end of FW and dorsal pattern, I narrowed species down to "lupina", "tenedia" and "mandana." Glassberg's Field Guide mentions that on Great Emesis "mandana", there is a lone HW finger that extends downward toward the PM band from the adjacent black band. This emesis does have that mark (notable on left HW) and that band matches up perfectly for this species. I should also note that this was a large emesis, which also supports Great Emesis.

Coordinator notes: All online photos of this species are redder or more orange than this photo, but the pattern matches better than two other similar species that could be considered in the future: Dark Tanmark, Emesis ocypore - and - Black-vented Silvermark, Metacharis victix, the latter which is more common in Costa Rica.
