Caterpillar frass

Description:

A strange pattern of frass? found on a well mined eucalyptus leaf. I was particularly fascinated by the 'star-like' arrangement on the leaf stem.

Habitat:

Open dry eucalyptus forest.

Recently found that a particular Oecophorid larva covers itself on a leaf with frass to pupate... one of the Wingia group.

Yes I agree it could be that although they seem to wear the frass as larvae...

Nice theory martin. It would be great to catch one early then and see it in action.

Argy Bee. I have seen these before and this is an unsolved mystery. I suspect a caterpillar building a fence of spikes on the petiole before it pupates. I have only seen them after they have departed, as yours also shows.
