How does a jumping spider experience the world? You can help us find out!
Complex multimodal signaling is prevalent in animal communication, but there remains very much to be explored regarding the function and evolution of such signaling systems. In this study we are testing the relative importance of different sensory modalities in determining courtship success in the jumping spider Habronattus formosus. Males of this species are notable for the presence of red third-leg ornaments, which are displayed during courtship dances, as well as for complex vibratory “songs” transmitted through the substrate as part of the courtship display.
We will collect 200 of each immature females and males of Habronattus formosus at Lake Berryessa and raise them to sexual maturity in the lab. We will conduct courtship experiments to determine the probability of mating in the lab under the following conditions: 1) control (no manipulations), 2) Red light excluded, 3) Vibrations excluded, 4) Vibrations and red light excluded. The results of this experiment will be informative in classifying the role of multimodal signaling in H. formosus courtship and could give insight into the processes underlying the signal evolution. Furthermore, to better understand the ecological significance of color vision in jumping spiders we will conduct prey capture experiments in which we will quantify spider hunting success under different lighting conditions.
