Poplar Hawk-moth (Laothoe populi) larva.
On first hatching the larva is pale green with small yellow tubercules and a cream-coloured tail horn. Later, it develops yellow diagonal stripes on its sides, and pink spiracles. Individuals feeding on willows may become quite heavily spotted with red. Others are more bluish white with cream stripes and tubercules. They are stout bodied, and grow to 65–85 mm.
