The morphology and spectral characteristics of the compound eye of (Selman & Vogt, 1971) (Coleoptera, Chrysomelidae, Galerucinae, Alticini).

The first exploratory study was conducted on the compound eye morphology and spectral characteristics of (Selman & Vogt, 1971) to clarify its eye structure and its spectral sensitivity.
