DISTRIBUTION:

Attacus crameri (named for Peter Cramer) flies in the central Moluccas of Indonesia: Ambon, Batjan, (Buru; now probably A. siriae), Ceram (Seram), Saparua.

Males have forewing lengths of 118-122mm. The fenestrae are small, almost always single and almost completely filled with yellow scaling in the tail-like extension.

The female forewing length is 131-138mm. Fenestrae are much larger than those of male, but still generally do not meet the postmedial lines. The hindwing outer margin is quite scallopped.

Note the strong presence of a yellow inner lining of the fenestrae and the tail-like extension of the inner, lower apex of the fenestrae on all wings.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Specimens have been taken in January, April-May, and August-December.

Life cycyle is unknown.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the posterior tip of the abdomen to call in night-flying males.

EGGS, LARVAE, COCOONS, AND PUPAE:

Eggs are relatively large and larvae pass through at least five instars, spinning a double-walled cocoons which hang from a tree branches via a strong silken peduncles.

Larval Food Plants

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
