Synopsis:
Many animals have body parts that reflect ultraviolet (UV) light. In animals that exhibit sexual dimorphism, UV-reflecting markings are commonly involved in intra-specific interactions. Therefore, it is often suggested that the evolution of these traits might be the consequence of sexual selection. Over the past three decades, it has been well established that male ornamentation falls under direct selection through female preferences in many animals, including birds, fishes, reptiles, insects, and spiders. In this talk, I will first provide a brief review on colour vision, particularly UV vision, UV coloration and the perception of UV coloration in jumping spiders (Araneae: Salticidae). I will then highlight our recent studies on the role of different UV colours in female mate choice and their relative importance in sexual selection in salticids. Finally, I will shed light on the mechanisms of UV color production. Taken together, I’ll share with you about how jumping spiders see the world through their eyes.
