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.
@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?
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.
@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.
