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 gelIntenziteto obarvanosti kril metuljčnice (Libelloides macaronius) smo določali z absorpcijo svetlobe; pri valovni dolžini 425 nm za rumene dele kril in pri valovni dolžini 650 nm za črne dele kril. Razlike med samci in samicami niso bile statistično pomembne. V črnih delih kril smo dokazali črni pigment melanin. V obeh delih (rumenih in črnih) je bil prisoten rumen pigment sepiapterin in še en neidentificiran rumen pigment. Ekstrahirali smo ju z 0.4% saharozo in analizirali s papirno in tankoplastno kromatografijo na silikageluTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaPrirodoslovni muzej Slovenije
