Orecta acuminata, CATE Sphingidae

There appears to be considerable fading of grab green to orangey brown as specimens age.

In the nominate subspecies, the forewing apex is quite produced and bluntly pointed, but not truncated or excavate as in Protambulyx and Adhemarius species. The forewing pattern is highly variable, ranging from a highly contrasting series of lines and patches to almost unmarked. Slightly darker, dentate median and post median lines are followed by a suffusion of light greyish-white, diffuse scaling.

Also in the nominate subspecies, the dark colouration on the thorax is a good match for all of the following forewing characters: 1) small basal dot near body;, 2) broad, distal basal band not quite reaching the costa; continuing with 3) a separate, slightly distal suboval patch bordering the lower edge of the costa; 4) a small preapical parallelogram on and below the costa, broken by thin white line on lower edge of the costa; 5) a subtrapezoidal patch along the inner margin, atop the slightly excavate region preceeding the anal angle. On the hindwing there is same coloured small dot near the anal angle. All of the dark regions, including the thoracic areas are outlined with thin white lines.

The lighter colouration of the thorax (shoulders and center) is a good match for the following areas on the forewing: 1) most of the costa except for the darker, preapical parallelogram; 2) upper sixth of median area; 3) an elongate costal apical patch distal to paralleogram; 4) a region atop the darker trapezoidal patch along the inner margin; and on the hindwing the same colouration in a diffuse band along the slightly crenulate outer margin from the small dot near the anal angle, running approximately half way to the apex.

The forewing cell spot is not prominent, being masked by a slightly darker region.

In subspecies Orecta lycidas eos, the median and post median lines are more prominent (darker), more broadly diffuse and are without the outer suffusions of greyish-white scales. The dark markings are not accentuated with a thin, yet distinct greyish white outline as in the nominate subspecies. The cell spot is much more distinct although diffuse.

The overall forewing ground colour is more consistent in eos, but in both species the forewing subterminal and terminal areas are dark.

The specimen depicted in Hawkmoths of Argentina is a good match for Orecta lycidas eos, but it is not as boldly marked as the image supplied by Leonardo Aguado, which may be something not yet described.

determination (tentative) and notes (blue and green) above, by Bill Oehlke.

I feel the specimen from Entre Rios, although more boldly marked, is consistent with wing shape and general characters of Orecta lycidas eos. I believe Orecta acuminata is found only in north western Argentina and Paraguay and has forewings with apices much more narrowly produced. Those two species, along with nominate lycidas, are the only Orecta reported for Argentina. Perhaps the image supplied by Leonardo is of a species or subspecies not yet described.


Orecta lycidas eos adults are on the wing in Entre Rios in November (LA).

Orecta lycidas eos larvae feed upon plants in the Lauraceae family.
