The larvae feed on Oleander (nerium), and Periwinkle (vinca sp), a common ground cover plant and will usually take Privet.
If the larvae will not accept Privet, cut up some Periwinkle / Oleander leaves and soak them in water for a few hours until the water obtains the flavour of the Periwinkle.
This should then be sprayed onto a sprig of Privet and allowed to dry before offering it to the larvae.
Another way is to break Periwinkle leaves and rub the privet leaf with the broken leaf.
