Superfamily: Bombycoidea, Latreille, 1802
"Asian Spring Blossoms"
Females extend a scent gland from the posterior tip of the abdomen to call in night-flying males whose undersides are as colourful and striking as the dorsal patterns.

Eggs are relatively large, round, slightly flattened dorsally and are covered with a reddish brown glue.

Eggs are deposited singly and the larvae are solitary feeders.
The first instar larvae are striped as are most of the Attacus and Samia species.

In the second instar there is a heavy buildup of waxy powder of scoli and body.
Larvae like warmth and humidity and prefer ailanthus, but privet is serving quite well for this larva.
In a short while, the secretion of waxy powder will offer this newly moulted larva some protection as it moves through the foliage.
Larvae progress rapidly in warm humid conditions and do not like cooler, dryer conditions often encountered in captive rearing situations.

The pinkish red patch on the "anal claspers" becomes quite distinct as the larvae progress.
A fine white powder covers larvae after each moult but quite a bit rubs off as they crawl through foliage.
This fifth instar larva is getting ready to spin a cocoon that will be double-walled, as per the Attacus species, but edwardsii larvae tend to incoroporate twigs and leaf stems into the spinning.
