Behaviors associated with mating success in the “purring” wolf spider Gladicosa gulosa

Abstract
Studies of sexual selection in animal systems frequently use courtship and receptivity behaviors as metrics for mating success, and this is generally built upon data associating such behaviors with mating. Spider systems are becoming increasingly popular in sexual selection research, and the wolf spider Gladicosa gulosa has the potential to help answer unique questions in animal communication. However, this species is understudied, and no quantitative data exist that demonstrate which male and female behaviors may be indicators of mating success. We paired male and female G. gulosa and recorded the behaviors involved in their courtship and mating. We found a number of significant behaviors from both males and females, and we suggest which behaviors/variables are perhaps most predictive of mating success. Beyond building a data‐based foundation for future work, we also suggest that the relationship of certain male and female variables may shed light on some of the more unique features of this species.
