Attacus is a genus of moths in the family Saturniidae. The genus was named by Carl Linnaeus in his 1767 12th edition of Systema Naturae.[1]

The genus contains the

Atlas moth (Attacus atlas), and Attacus caesar, the second and third largest known moths (in terms of wingspan), though different sources treat one or the other as slightly larger. Both are outclassed by the largest, (in terms of wingspan) moths, Thysania agrippina, also known as the White Witch Moth.[2][3]

Like other saturniid moths, adults lack a fully formed digestive tract and do not feed.

Habitat

The moth's preferred habitat is primary forest and the forested lowlands around the vicinity of their hostplants. They are

Ligustrum, Ailanthus, Prunus, Syringa and Mussaenda
.

Life cycle

Their life cycle is similar to any other

desiccate
the hapless pupa. It molts for the last time, and turns into a large brown pupa. In this state, it will take approximately 1.5-2 months to emerge as a full grown adult. Then it will fly off into the jungle, to find a mate, breed, then die.

Mimicry and appearance

Adult moths are predominantly anywhere from cinnabar red to brick red, some even going into deep crimson red. The wingtips of many species mimic the head of a snake, and when threatened the moths will drop to the ground and slowly shake their wings, revealing the "snake head" and hopefully scaring would be predators away. They also have small transparent 'windows' in the middle of their wings.

Their caterpillars are pale green, fleshy, and have large wax covered spines. Younger instars are nearly mint colored, adorned with small blue flecks. As they grow, they become more solidly colored and lose their blue coloring, except on their

prolegs
and feet.

Species
Male Attacus dohertyi from Timor
