All the lovely pink and green has worn off. Elephant hawmoths are coloured to camouflage with Rosebay Willowherb (the caterpillars' food plant). Newly emerged moths are absolutely stunning and you are lucky to find it.
Later in the year, look out for the caterpillars getting ready to pupate. The 'elephant' part of their name is due to them looking like an elephant's trunk. But with eyes! Fascinating creatures, and their poo is the size of peppercorns!
