Notes Spiders fighting or mating? Robb Bennett has identified this spider and the other in this series as mating Agelenopsis species. He can add comments for these.
Review Comments Male. See comments on 83628. Species identity of these Agelenopsis spiders can be determined through the shape of the male's "embolus", the narrow, dark, curved structure clearly visible on the male's left pedipalp (structure in front of the male's face close to the right hand margin of the image, not quite so visible on the male's right palp a little bit left and lower in the image. In another of Catherine's images (not posted here, unfortunately), the curved tip of the embolus (characteristic of male Agelenopsis potteri) is clearly visible. Without being able to see the embolus and its curved tip, it would be nearly impossible to decide which of the 5 species of Agelenopsis known to occur in BC this beast belongs to. Except for their genitalic characteristics, all Agelenopsis species look very similar.
