DISTRIBUTION:

Protambulyx sulphurea (Wing span: approx. 103-110-118mm), flies in
northern and southwestern Venezuela (specimen type locality); and in
French Guiana: Kaw. It has also been recorded in Bolivia: Beni (235-1000m);
Brazil: Rio de Janeiro.

This species was originally described as an aberration of Protambulyx eurycles, but it is more similar to Protambulyx ockendeni with narrower and paler wings, and a less contrasting pattern. The forewing lackings the large costal patches and subbasal patch on the inner margin of Protambulyx ockendeni.

The hindwings are lemon yellow.

On the ventral surface the forewing marginal band is much narrower than in Protambulyx ockendeni, especially below M3.

Protambulyx sulphurea adults probably fly throughout the year.

Adults nectar from flowers.

ECLOSION:

Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

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

EGGS, LARVAE, PUPAE:

Larvae feed on

Moths may eclose within fourteen days of pupation.
