This 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.

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 and dedicated to Ezequiel Osvaldo Nez Bustos who has sent me many images of Sphingidae with data from Argentina.


Aleuron chloroptera
No black belts around adomen
Almost uniform drab grey-green with nine, weak, more or less evenly dentate transverse lines between base of CuA2 and outer margin.
Small, darker crescents in submarginal area.

Aleuron neglectum
Similar to iphis.
Abdominal white belt much narrower than in iphis. Fw: black median lines indistinct posteriorly, except the basal most, which is bordered white basally but not distally, except at costal margin.


Enyo lugubris
Body, wings dark brown.
Fw: large black patch covering most of outer half of wing.
Pale tan cell spot with small dark inner pupil,
Fairly straight median line to inside of cell spot.

Enyo gorgon
Forewing apex produced, with concave outer edge, not straight cut as in Enyo cavifer.
Lower half of wing noticeably darker than upper half.

Enyo ocypete
Fw: dark area not sharply defined, prolonged along antemedian line to posterior margin.
Discal spot small.
Male hw: diagnostic pale yellowish-white anal patch.
Females similar to Enyo lugubris lugubris, but have broad brown belt across base of abdomen (this belt either very narrow or absent in Enyo lugubris lugubris).


Pachylia and Pachylioides

Pachylioides resumens
The forewing tip is hooked. The upperside of the forewing is gray-brown with dark brown incomplete wavy lines and dark brown and orange shading. The upperside of the hindwing has orange shading and dark brown patches at the tip and in the center.

Pachylia ficus
The upperside of the forewing is orangish brown with a paler patch along the costa at the tip. The upperside of the hindwing is orange to orangish brown with a black outer border, a black median band, and a white spot on the outer margin near the body.

Pachylia syces syces
Ground colour is orangey-brown to grey-brown to dark brown with much paler patches in the cell and apical regions, along and below the costa. Numberous, irregular, faint lines run from the costa to the inner margin. Hindwings also have a white spot on outer margin near anal angle.



Unzela japix discrepens has a forewing with distinct patches of different colours.
