1665 Pseudoterpna pruinata (Grass Emerald)

Geometridae, Geometrinae - Wingspan: 36mm.


One of a number of species which are grouped under the common name as "Emeralds". A common, but sporadic species which is widespread in Cornwall where-ever it's larval foodplant, Gorse, which is widespread here, occurs. The above picture shows a newly emerged specimen, but in time it fades to a pale brownish-green, so can often look quite different from illustrations.
