Euchalcia bellieri is a moth of the family Noctuidae.
Latin species name bellieri honors the French entomologist Jean-Baptiste Eugène Bellier de la Chavignerie (1819-1888).[3]
Euchalcia bellieri has a wingspan of about 33–34 millimetres (1.3–1.3 in).[3][4] This rare species closely resemble Euchalcia variabilis, but it is quite smaller. The upperside of the forewings shows a well marked oblique inner line with a slight rosy border. The central area is dark brown, while the hind margin is rosy. The basal dark line is angulated. The orbicular stigma is double, with a yellow ring. Larvae are green with a white lateral line.[5]
Caterpillars feed on Delphinium dubium, maybe also on Aconitum species.[6] They are fully grown at the end of June, while adults fly in July.[5]
This species is endemic to France (Hautes-Alpes, Basses-Alpes, Alpes Maritimes) and to a northern Italian Region (Piedmont).[7][8]
