Smerinthini thumbnails

Smerinthini of CostaRica:
Adhemarius, Orecta and Protambulyx

This very tentative checklist will become more accurate as images and information are sent to me. If you would like to assist in the development of this worldwide Sphingidae data/image base, please send info and images to Bill Oehlke.

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.

Adhem. dariensis
prominent, dark, oblique, pm line quickly distinguishes this species
the wide, dark, basal band does not meet the lower edge of the costa

Adhemarius ypsilon
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

Adhem. fulvescens
browner species than gannascus or daphne interrupta
dark, apical mark wider than gannascus
dark basal band reaches upper edge of costa

Adhemarius gannascus
dark area on basal costa continuous to inner margin
forewing less produced than in dentoni;
dark apical area reduced to thin comma

Adhemarius daphne
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

Orecta venedictoffae male, Costa Rica, courtesy of Dan Janzen,
also flies in Ecuador; unconfirmed in Colombia??
Orecta venedictoffae : note produced, pointed apex.

hw pml inwardly concave in upper 1/3

Protambulyx goeldii
Fw o. m. broadens inwardly between veins M1/M2 with smooth inner edge;
prominent dark spot at cell apex
prominent greenish brown suffusion along and just below costa;
hw pml almost straight in upper 1/3
lacks hw median line

Protambulyx s. strigilis
Fw o. m. non-broadening twixt M1/M2
small basal dot above fw i. m.
markings emanating from costa mostly thin irregular streaks rahter than wider, more diffuse and darker, irregular clouds
hw pml leaves costa at right angle
