While on holiday in Tenerife I managed to snap a few of the local lizards with my UV camera. Unfortunately I only had a 35mm lens with me (Novoflex Noflexar), so had to be very close to the lizards and the most colourful big males were too shy to let me get within a metre or so. But I did manage to snap a few. The dusky blue patches on the cheeks and flanks of the males have quite intense UV reflection and really stand out in UV-vision. This highlights the covert sexual signalling of the lizards, where their bright colours are more conspicuous to potential mates than to potential predators (Kate recently published a cool paper on this in her Aegean wall lizards). The photos were all processed using my image analysis toolbox.
