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).[1]
Euchalcia bellieri has a wingspan of about 33-.[1] [2] 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.
Caterpillars feed on Delphinium dubium, maybe also on Aconitum species.[3] They are fully grown at the end of June, while adults fly in July.[4]
This species is endemic to France (Hautes-Alpes, Basses-Alpes, Alpes Maritimes) and to a northern Italian Region (Piedmont).[5] [6]
