Spiders of the genus Trochosa are significantly larger than those of Pardosa. They are hunting spiders that are active at night. In addition to the size difference the genera Trochosa and Pardosa can be distinguished by the position of the posterior lateral eyes, which are relatively further apart on Trochosa than on Pardosa compared to the separation of the median posterior ones.
