Elephant Hawkmoth caterpillar (Dielephila elpenor)

Caterpillar of the Elephant Hawkmoth (C Robinson, Trap Grounds, 7 Sept 2019)

Spotted by Alan Allport on 7 September feeding on Rosebay Willowherb. Three inches long! It will pupate in a couple of weeks' time and overwinter under the ground; but will we see the spectacular pink-winged adult next summer? Not likely, because it is a nocturnal moth.
