DISTRIBUTION:

Manduca violaalba (wingspan: 73-83mm; forewing length: approximately 39mm) flies in cerrado habitats in Brazil (specimen type locality) in Mato Grosso; Mato Grosso do Sul; Goias; Maranhao: Federal District; Minas Gerais.

This species should be easy to identify due to almost completely uniform dark grey-brown almost black ground colour of the forewings. Markings are dark black and distinct and there usually is a small white dot in the cell area.

The hindwing is white with a dark, dentate band along the outer margin.

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.
