User's notes

Cocoon removed and dissected. Pupa still in it’s case was deceased with a hard, crumbly texture. Many burrow holes present. Added tree sighting ID. Can also confirm that the black hairs on the cocoon can pierce skin and are difficult to remove due to their brittleness. Sites are mildly painful while hairs are embedded.

I think Saturniidae cocoons are rounder, darker and firmer than this.

@donhe @ibaird I had a look on http://lepidoptera.butterflyhouse.com.au/anth/chalepteryx.html and the cocoon looks different, plus the sighting was on a eucalyptus which doesn’t seem to match their food. There were 3. Could it be something else? Is it worth me trying to remove one and bring it home to rear?

@donhe @ibaird maybe http://lepidoptera.butterflyhouse.com.au/anth/collesi.html?

@donhe and @ibaird I’be updated the photos, description, associated tree with more info. Can you check that the ID is consistent? Thanks!

I couldn't see the brittle hairs in the photo, but those are characteristic of C. collesi.

@donhe I’ve added a close up of the cocoon with black hairs

There are 2 related species Chelepteryx collesi (feeds only on Gum) and Chelepteryx chalepteryx (feeds on Wattle, Exocarpus and Pinaceae). Both have camouflaged cocoons like this. Saturniidae have dark globular cocoons.

I am confused. Was it on Gum or Pine? Was it 2cms long or 12 cms long

@donhe sorry. It was on a yellow box. Cocoon is 12cm, pupa case is 4-5cm. I dissected 2 - the first had hatched already and the second was desiccated. I’ve fixed the photos.
