Pseudoterpna coronillaria

Pseudoterpna coronillaria, the Jersey emerald or gorse emerald, is a moth of the family Geometridae. The species was first described by Jacob Hübner in 1796. It is known from Spain, Portugal, the Pyrenees, western and southern France, Corsica, Sardinia, Sicily, Italy, Samos, Rhodes, Turkey, Israel, Lebanon, northern Jordan and North Africa. It has not been reported from mainland Great Britain, but is present on Jersey, where it was previously overlooked as a form of the grass emerald, until 2001 when it was correctly identified.
