Ribbed case moth

?Hylarcta nigrescens


Super cute about 10mm tall case made with regular scale shapes around a small cone.


On eucalyptus leaf in a local nature and games reserve.


Maybe Ribbed Case Moth - Hyalarcta nigrescens or may never know. Many of these are adept at utilising whatever plant they are currently occupying although the beginnings of ribs seem to be there.

Cool spotting, Mark. Very Disneyesque! That would make someone a lovely hat! ;)

Thanks Jae.
Also thanks Orni for the suggestion but if I can't see the head pattern it's not certain. H.nigrescens is definitely a good chance though.
