Functional significance of the optical properties of flowers for visual signalling
Background Flower coloration is a key enabler for pollinator attraction. Floral visual signals
comprise several components that are generated by specific anatomical structures and …

Bumblebees (Bombus terrestris) and honeybees (Apis mellifera) prefer similar colours of higher spectral purity over trained colours
K Rohde, S Papiorek, K Lunau - Journal of Comparative Physiology A, 2013 - Springer
Differences in the concentration of pigments as well as their composition and spatial
arrangement cause intraspecific variation in the spectral signature of flowers. Known colour …

Detection of coloured patterns by honeybees through chromatic and achromatic cues
We asked whether the detection range of two-coloured centre-surround patterns differs from
that of single-coloured targets. Honeybees Apis mellifera were trained to distinguish …
