Yes they walk up to 20 metres from their foodplant, then burrow under the soil up to 15 centimetres down. Bear in mind also that about 99% perish before reaching adulthood, due to viral, bacterial, fungal disease, or infection by wasp and fly parasitoids, or predation by birds, spiders, ants, mantids, shield bugs, assassin bugs etc.

I note that Fraxinus angustifolia is in Oleaceae, as is Privet.

Fraxinus angustifolia, Oleaceae, as is Ligustrum vulgare, so probably P. casuarinae.

Privet hawk moth. I have usually found it on desert ash, never on privet.
