Female mating rates and their fitness consequences in the common house spider Parasteatoda tepidariorum

ABSTRACT: Abstract Mating systems, with varying female mating rates occurring with the same partner (monandry) or with multiple mates (polyandry), can have far reaching consequences for population viability and the rate of gene flow. Here, we investigate the mating rates of the common house spider Parasteatoda tepidariorum (Theridiidae), an emerging model for genetic studies, with yet undescribed reproductive behavior. It is hypothesized that spiders belonging to this family have low re‐mating rates. We paired females twice with the same male (monandry) or with different males (polyandry), and recorded behaviors, mating success and fitness resulting from single‐ and double‐matings, either monandrous or polyandrous. Despite the study being explorative in nature, we predict successful matings to be mo
