Hercules Moth (Coscinocera hercules)

Family Saturniidae  (Tropical North Queensland, New Guinea)

The adult moth has a wingspan of ca. 27 cm it is the largest moth found in Australia and one of the largest in the world. The 1st instar caterpillars are however astonishingly tiny and incredible cute! They will go through 6 larval stages and grow to 12cm with a weight of up to 30g before they spin cocoons and pupate in a long double-walled silk cocoon.  (I found reports of some captive bred individuals that apparently had reached almost 15cm and 53g.)

The adult moth lives only a few days (4-5). The caterpillar can however live up to 3 months. The grow rapidly. These caterpillars went from hatching to 5th instar in only 5 weeks. Growth will however be strongly influenced by temperature and food availability.

The caterpillars feed on various rainforest trees but prefer those of the Bleeding Heart tree (Omalanthus nutans).  Other accepted foods include Celery Wood ( Polyscias elegans), Tree of Heaven ( Ailanthus altissima), Cheese Tree ( Glochidion ferdinandi), Red Bean (Dysoxylum muelleri), Black Cherry ( Prunus serotina) and Queensland Apple ( Timonius rumphii).

In captivity caterpillars have been successfully raised on Walnut ( Juglans regia), Privet ( Ligustrum vulgare), Lilac ( Syringa sp.), Willow ( Salix sp.)  and Tree of Heaven (Ailanthus altissima).

Caterpillars also need to drink.

The adult moths do not feed as they have no mouthparts.

eggs

The eggs are tiny and orange in color. They seem to resemble leaf galls in size and color.  The female glues them single or in small clumps onto (or in proximity to)  suitable host plants.  After about 2 weeks tiny caterpillars hatch.

Pupae

The caterpillars of the Hercules moth pupate in a long double-walled silk cocoon.

Adult

The adults don’t feed and live only for a few days. Both, male and female can fly. However the more lightly built male will search for the female and do the flying. The female will emit pheromones to attract a male. These scent molecules can be detected by the male over large distances.

Males have long wing tails and feathery antennae. Females are heavier set and have no wing tails.
