Timing and patterns of mating in a free-ranging population of Lycosa tarantula (Araneae, Lycosidae) from central Spain

Abstract

We analysed the timing and patterns of mating in a free-ranging population of the wolf spider Lycosa tarantula (Araneae, Lycosidae) in central Spain monitored during a whole reproductive period. The population showed a polygamous mating system. However, the frequency of multiple mating was relatively low. Reproductive success of males was highly skewed, as a few males monopolized most of the copulations recorded. Males matured slightly before females but male and female maturation largely overlapped. Mortality of subadult spiders was independent of their sex, and the operational sex ratio was 1:1. Early maturation of females resulted in a larger number of visiting males but not higher mating success, indicating the possibility of female mate choice in this species.
