Hemistola chrysoprasaria
species of insect

Hemistola chrysoprasaria, the small emerald, is a moth of the family Geometridae. The species can be found in all Europe including the Iberian Peninsula and Russia East to the Ural Mountains, North Africa, Asia Minor, Transcaucasia and the mountains of Eastern Asia (Russian Far East, Siberia), (Amur, Ussuri) and China Tian Shan (as form lissas)
Description
The wingspan is 28–32 mm. Both forewings and hindwings are light-green coloured, but fade with increasing life span to yellow-green to yellow-white. There is an outer and a fainter inner, slightly curved and continuous, white cross line on the front wings. The inner (antemedian) is strongly curved and usually with two small, slight teeth directed distad, the outer (postmedian) is nearly parallel with distal margin, not dentate. The outer line continues on the hindwing. There is no discal stain. The antennae of the males are slightly combed, those of females short ciliate. In Amur and Ussuri the specimens are often large and with the lines rather widely separated. Lissas differs in the shape of the hindwing, which is rounded instead of elbowed
The fresh egg is green color and discolours into dark tints just before hatching.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Hemistola chrysoprasaria”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 26, 2025. The linked authority identifier is Q2325664. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
