DISTRIBUTION:

Manduca brunalba (approximate wingspan: 100-104mm) flies in
Brazil (specimen type locality);
French Guiana: Kaw; Montsinery
Peru;
Venezuela. In
Bolivia it is recorded from Yocumo [Yacuma] (350m), Department of Beni.

It is likely also present in Suriname and Guyana.

The slightly darker tegulae are inwardly lined in thin black. On the centr of the thorax there are two small dark triangles. The abdomen has three prominent orangey-yellow marks on each side and a dark mesial band, broken into segments.

The forewing median area is a blotchy dark brown in its upper 3/4 with a strong outward projection opposite the cell. There is a conspicuous, continuous white postmedian band lining the outer edge of the median area. A dark irregular am line, more visible in its lower 2/3 is highlighted by white scaling on both sides.

FLIGHT TIMES:

Manduca brunalba adults fly in August in French Guiana and possibly in other months.

ECLOSION:

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

SCENTING AND MATING:

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

EGGS, LARVAE, PUPAE:

Larval hosts are unknown by me.
