Javan Oak Silk-Moth (Antheraea jana) | EGGS

Antheraea jana is a striking species of silk moth belonging to the family Saturniidae, and part of the Oak Silk-moth genus. Known for its impressive size and captivating wing patterns, this moth is native to tropical and subtropical regions of Southeast Asia - it has been several years since we last had livestock. The wings of female  jana are highly variable in colour - in shades of yellow, grey, brown, orange - adorned with large, eye-like markings that serve as a defense mechanism against predators. Males typically occur in shades of orange with smaller eyespots but are nonetheless highly patterned. The adult moths are nocturnal and have vestigial mouthparts, meaning they do not feed during their short lifespan, which is dedicated to reproduction.

This moth is sometimes reared for its silk in Asia, however it has not often been reared outside of its native range. Some have reared caterpillars successfully using Birch (Betula), Eucalyptus, and Sweet Gum (Liquidambar), although reported host plants on butterfly farms include Avocado and Cinnamomum. Being a member of Antheraea, it may also accept Hawthorn (Crataegus) or Oak (Quercus) however we have not tried either of these options and have previously obtained good results using the aforementioned Liquidambar and Eucalyptus. Breeding occurs easily with good air flow to distribute pheromones, allowing the male to effectively locate the female moth. 

Difficulty - Easy (2/10) although limited data on rearing caterpillars.
