Family: Geometridae

Subfamily: Larentiinae

Taxon: Aplocera efformata

The most reliable separating characteristic on males is that plagiata has elongated, pointed claspers giving rise to a narrow abdomen tip: efformata has a blunter tip to the abdomen with rather shorter, curved claspers.Larva feeds on St John's-worts Hypericum sp.
