DISTRIBUTION:

The Five-spotted hawkmoth, Manduca quinquemaculatus (Wing span: 3 9/16 - 5 5/16 inches (9 - 13.5 cm)) flies in tobacco fields, vegetable gardens, and wherever host plants are found within its range, generally from Nicaragua: Managua; Mexico north throughout most of the United States and occasionally southern Canada, but it is uncommon in the Southeast and the Great Plains. There are reports from Hawaii and Brazil and Uruguay. I have never seen one on Prince Edward Island, Canada, but frequently saw them nectaring at railroad-side phlox at dusk or at lights in New Jersey. The moth abdomen usually has five but sometimes six pairs of yellow bands. The upperside of the forewing is blurry brown and gray. The upperside of the hindwing is banded with brown and white and has two well-separated median zigzag bands. The forewing fringes are grayish, not distinctly spotted with white. The specimen type locality is England.

FLIGHT TIMES:

Manduca quinquemaculatus adults fly as several broods from February-October in Florida and from April-October in Louisiana. There are at least two broods from May-October in the rest of the range.

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. The adults nectar from flowers including Japanese honeysuckle (Lonicera japonica), petunia (Petunia hybrida), bouncing bet (Saponaria officinalis), tobacco (Nicotiana), and phlox (Phlox).

EGGS, LARVAE, PUPAE:

Adults fly at dusk, and females deposit eggs singly on the upper surface of host plant leaves. The caterpillars are called Tomato Hornworms and each has a black horn at the end of the abdomen. Caterpillars have huge appetites for leaves and fruits and can defoliate plants quickly. Fully-grown caterpillars pupate and overwinter in soil burrows.

Larvae feed on potato, tobacco, tomato, and other plants in the nightshade family (Solanaceae).

Larvae also exhibit a dark form and in some specimens, both green and dark forms, there is a cream coloured supspiracular line and an extra half slash on the last abdominal segment as per David Bygott's image from Arizona.

Images of pupae courtesy of Tim Dyson. Larvae will pupate without soil in a tightly lidded plastic tub under loose paper towels. They should not be handled until they have hardened (a few days after they have darkened). The long curved projection from the head to the first section of the abdomen houses the proboscis or feeding tube.

Caterpillars have many natural enemy. They are beset by many parasitoids and predators. Eric Runfeldt sent me a short but graphic account of an attack by Polistes fuscatus, a paper wasp, on one of the Manduca quinquemaculatus larvae in his garden.
