Description

Pardosa laura is a medium-sized wolf spider with notable sexual dimorphism in coloration. Adult females measure 4.0–7.2 mm in body length, while males are smaller at 3.7–5.2 mm.
The carapace of females is dark reddish-brown, while males are almost entirely black. The anterior median eyes are slightly larger than the anterior lateral eyes. The clypeus is pale yellowish-brown and wider than the diameter of the anterior median eyes. The maxillae and labium are greyish-brown.
In females, the sternum is pale yellowish-brown with a reddish-brown U-shaped marking in the central area, while in males it is blackish-grey with a narrow yellowish-brown longitudinal stripe in the upper central portion. The dorsal abdomen of females is yellowish-brown with irregular dark brown markings, while males have a reddish-brown abdomen with six pairs of black spots arranged in rows on the posterior half.
The legs are generally yellowish-brown with ring patterns visible from the femur to the tibia, except for the whitish-yellow coxae and the dark brown tips of the first leg patellae. The pedipalps are dark brown except for the yellowish-brown patella, with white hairs at the tip of the femur and base of the patella, and numerous black hairs at the tip of the tibia.

Life cycle

Adult females can be found from May to mid-September, while males have a shorter active period from May to early July. Egg sac formation occurs in July.
