Oleander hawk-moth caterpillar (likely)

Warm regions of Africa, southern Europe, Asia, and introduced areas; found on oleander and related plants in gardens, scrub, and woodland edges.

Larvae chew leaves, especially oleander (Nerium oleander), periwinkle (Vinca), and related Apocynaceae. Adults feed on nectar from tubular flowers.

The caterpillar is nocturnal or crepuscular and often rests inconspicuously along stems during the day. It pupates in leaf litter or loose soil; adults are strong, fast-flying moths active at dusk and night.

It is not dangerous to handle, though oleander toxins may remain in its body after feeding, so it should not be eaten. It contributes to food webs, and adults are important nocturnal pollinators.
