Intensity of wing pigmentation and identification of pigments in wings of owl-fly Libelloides macaronius (Scopoli, 1763) (Neuroptera: Ascalaphidae)Senčič, Leon (Avtor) entomologyowl-flywingscolorationpigmentssepiapterinmelaninColoration intensity of wings from owl-fly (Libelloides macaronius) was checked with absorption of the light; at 425 nm of the yellow parts of the wings and at 650 nm of the black parts. The difference between males and females was not statistically significant. In black parts of wings the black pigment melanin was identified. In both parts (yellow and black) the yellow pigment sepiapterin and one unidentified yellow pigment were present. They were extracted with 0.4% sucrose and analysed on paper and thin-layer chromatography on Silica gel.Slovensko entomološko društvo Štefana Michielija20062015-07-10 21:10:42Znanstveno delo53550sl
