Larva 1 eclosed last night and it is an Eupanacra species. It looks very much like E. mydon, but here I am in a quandry.
Moths of Borneo shows a photo of the larva of Panacra mydon (same species) which is very different. See here.
There is a very similar species, E. elegantulus, but I have never seen the larva of this species.
