I went for a wander through the paddocks late yesterday. I think it was a bit early for them to be out feeding. I eventually saw oodles of Pterolocera sp larvae, no Anthea sp. I've only recorded A. acuta, nicothoe & ocellata moths here so far.
A. basigera has white dots like that but i think its hairs are paler than this one. Maybe it is one of A. basigera's relatives : A. euryphrica or A. oressarcha. Not enough Anthela larvae have had the portraits published to sure of any of them.
