CARL MARSHALL: Actias selene catterpilars



 The Indian moon moth Actias selene is one of the most Popular silk-moths to rear in captivity. Its popularity is a result of the relative ease of the larval stage, coupled with the stunning sight of the newly emerged moth which being a silk-moth does not feed. The adults are also very easy to pair, so multiple generations can be achieved.

Its one of the most beautiful of all the silk-moths, with a large wingspan and subtle pale green and pink colouration.
The larval stage is also very rewarding for the rearer, as the larvae are truly spectacular and change colour throughout their development; newly emerged larvae are black and red, quickly changing red in their second instar, and then finally turning green in the final instar. The larvae grow to a very impressive size (as can be seen in the illustrations), easily reaching 12cm or more.

When fully grown, they pupate within a silken cocoon* spun up against foliage - see illustration.

They accept a wide variety of deciduous trees and shrubs in summer, and can continue to be reared throughout winter when rhododendron acts as an evergreen solution.   

*Contrary to popular belief butterflies do-not emerge from cocoons. During a butterflies pupal stage (Holometabolous) they are not encased in silk so should be referred to as a chrysalis or simply a pupa.   

A. selene moths coming soon!
