For now it is Rose as also observed by Jurgen.
Today, a couple of my A. isis lavae hatched. I offer them: Rose, Bramble, Eucalyptus neclecta, Hawthorne and Privet. My Liquidambar is now starting to leave, so I can not offer it yet. I will let you know what they took best.
Yes they take Ligustrum ovalifolium, but it's not their favorite. I placed Rosa in the cage and they are all starting to move from the Ligustrum to the Rosa. But it is possible to raise them on Ligustrum. That can be useful in the middle of the winter. But, in summer there are better foodplants.
A. isis take ligustrum ?
Is this ligustrum that you're using now?
