I have arranged the images in accordance with my perception of wing characters: predominent markings, shape, colour, size.
There are probably some Costa Rican species not listed below, and there are some species not officially confirmed for Costa Rica, although I think they have a good chance of being found there.
Females often have a wing shape or pattern that differs from the males. I hope some day to also have a thumbnail checklist for the females.
This page is inspired by Gernot Kunz who supplied me with many beautiful images of live moths from various provinces in Costa Rica in March, 2017.
Adhemarius ypsilon, Boca Tapada, Alejuela, Costa Rica,
prominent, dark, oblique, pm line quickly distinguishes this species
the wide, dark, basal band does not meet the lower edge of the costa
dark area on lower half of costa
merges with larger area to inner margin;
costa generally devoid of other dark patches except very large trapezoid near apex
browner species than gannascus or daphne interrupta
dark, apical mark wider than gannascus
dark basal band reaches upper edge of costa
dark area on basal costa continuous to inner margin
forewing less produced than in dentoni;
dark apical area reduced to thin comma
no dark area on basal costa
dark apical area broader than in gannascus
possibly limited to South America
A. dap. interrupta
no dark area on basal costa
Mexico to Costa Rica; very similar to gannascus, but interrupta has wider, dark, apical mark
