I haven’t seen them personally, but I’ve seen another photo like it. These are pupae of a Jezebel or Imperial White butterfly, Delias sp.
Thanks for the information. We found this similar looking image on The Victoria Museum site.
I have taken a photo in victoria of one just the same but with a white Imperial Jezabel on the web with the Pupae.
I have the exact same pupae with webbing in my front garden at the moment. I am in the Yarra Valley, Victoria.
So far I have two Imperial Jezebel butterflies that have not flow away? Is this normal? They have been there for a few days. I can send pictures if you like.
