TAXONOMY: Family: Sphingidae, Latreille, 1802 Subfamily: Macroglossinae, Harris, 1839 Tribe: Dilophonotini, Burmeister, 1878 Genus: Aleuron Hubner, [1819] ........... Species: carinata Walker, 1856

DISTRIBUTION:

Aleuron carinata, (wingspan 62-72-86mm), flies in
Brazil;
Peru;
Bolivia: La Paz, Santa Cruz;
Venezuela: Aragua;
Trinidad;
and northwards to
Panama TJ;
Costa Rica: Puntarenas (rare);
Belize: Stann Creek; and
Mexico.

Tylognathus philampeloides C. & R. Felder, 1867, Brazil, is same as Aleuron carinata.
orophilos Boisduval, [1875], Brazil, is same as Aleuron carinata.

The word "aleuron" is Greek for wheat flour or meal.

Easily distinguished from all other species of Aleuron (except Aleuron cymographum) by the black belts on the anterior margins of the abdominal segments dorsally; these are not visible when the segments are telescoped into one another, except for the two first belts, which are broader. Aleuron cymographum differs in having the pale apical patch of the forewing upperside delimited basally by a crenulated white line between the costa to M2.

Second labial palp segment very strongly angulate, much more so than in other species of Aleuron.

Male: First labial palp segment distinctly angulate laterally at apex.

Forewing upperside with nine more or less evenly dentate transverse lines between the base of CuA2 and outer margin.

Female: First labial palp segment slightly convex.

Forewing upperside with transverse lines between the base of CuA2 and outer margin very weak, except a median and a postmedian line, which are straight, parallel and prominent. CATE

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen.

EGGS, LARVAE, PUPAE:

Larvae feed on Doliocarpus dentatus , and Curatella americana, and probably other members of Dilleniaceae family. In the first instar the larva is green with an orange head and black hair-like tail as long as the body.

Caterpillars pupate in underground chambers. The pupa is black and orange and black spotted and ringed. The wing casings are clear orange. The venter of the thorax and the face are black. Pupal stage is usually about 23 days except for diapause during dry season.
