A Brief Introduction:
Macroglossum corythus luteata represents one member of Macroglossum, a genus with high biodiversity. The wing pattern of M. c. luteata is quite similar to M. sylvia and identification of the two species from wing pattern is very difficult. Characters on male genitalia are known to be the reliable way to distinguish M. c. luteata&M. sylvia.
