The human eye is insensitive to the angular direction of the light e-vector, but several animal species have the ability to discriminate differently polarized lights. How the polarization is detected is often unclear, however. Egg-laying Papilio butterflies have been shown to see false colours when presented with differently polarized lights. Here we asked whether this also holds in foraging butterflies. After training individuals to feed on nectar in front of an unpolarized spectral light, we carried out three dual-choice tests, where the discrimination of (i) the spectral content, (ii) the light intensity, and (iii) the e-vector orientation were investigated. In the first test, the butterflies selected the trained spectrum irrespective of its intensity, and in the second test they chose the light with the higher intensity. The result of the e-vector discrimination test was very similar to that of the second test, suggesting that foraging butterflies discriminate differently polarized lights as differing in brightness rather than as differing in colour. Papilio butterflies are clearly able to use at least two modes of polarization vision depending on the behavioural context.

Abstract Papiliochrome II, one of the yellow wing pigments of the Papilionid butterfly, Papilio xuthus, can be split into ʟ-kynurenine and a catecholamine derivative, SN-1, by 10-3 n HCI. The latter is hydrolyzed by ɴ HCI into β-alanine and noradrenaline. The structure of SN-1 has been elucidated as N-(β-alanyl)-ʟ-noradrenaline by NMR and MS data as well as by synthesis. Preparation of the N-hydroxysuccinimide ester of benzyloxycarbonyl-β-alanine, its condensation with ʟ-noradrenaline to the corresponding benzyloxycarbonyl protected SN-1 and of N- (β-alanyl)-ʟ-noradrenaline by hydrogenolysis of the protecting group are described.
