Pardosa palustris (LYCOSIDAE)
|
Pardosa palustris, in common with many of the hunting (or "Wolf" spiders) can often be seen running on the ground on hot days. It is difficult to distinguish from others in the genus Pardosa in the field, although its epigyne can easily be identified using a hand lens, by virtue of its large size and its not being obscured by hairs. To obtain a good view of the pedipalp it is usually necessary to dissect the pedipalp from the spider and lay it out so that a good ventral view is obtained. The photo is of an adult female. Males of the species are similar but a bit darker in appearance, and smaller. |
