(A, E) Mating pair of O. melania. (B, F) Mating pair of S. darwinianum. (C, G) Mature male of C. servilia with mature male of O. albistylum. (D, H) Mating pair of C. servilia. Each image photographed normally (RGB) (A–D) or through a UV filter (E–H) in the field. (I–N) Spectrometry of a round area (6 mm in diameter) on the 5th abdominal segment of O. melania (I, L), S. darwinianum (J, M), and C. servilia (K, N). (I–K) Male. (L–N) Female. Solid and dotted lines indicate averaged UV reflectance on the dorsal and ventral sides of the abdomen, respectively. The standard deviation is shaded.
