Drepana falcataria

Drepana falcataria, the pebble hook-tip, is a moth of the family Drepanidae.

The last instar caterpillar is green, the dorsum reddish brown, except towards the black-marked yellowish head.

In the younger stages it is blackish, with white marks on the fourth and seventh rings; later it becomes greenish below, and the markings on the back of rings four, seven, eight, and ten are whitish or creamy.

They prefer riparian forest and carr but are also found on the edge of moors and in parks and gardens.

The moth flies from April to August depending on the location.
