The Large Emerald, (Geometra papilionaria), is a moth of the family Geometridae. It is the type specimen for the family. It is found throughout Europe including the British Isles.
This is a large and attractive species, as the specific name suggests very butterfly like, with a wingspan of 50-65 mm. Newly emerged adults are bright green with darker green and white fascia, though the green colouration fades after a few days. It flies at night from June to August and is attracted to light.
The larva is brown at first, turning green later, and feeds mainly on birch though it has also been recorded on alder, beech and hazel. The species overwinters as a larva.
