狼豹蛛在林地附近活动，在落叶层中越冬。在冬季凋落物温度的现场记录表明，凋落物内的温度波动远小于那些在表面上，空气温度越低，表面凋落物和深层凋落物的温度之间的差异越大。在实验室建造的凋落物堆中，当温度降低到冰点以下时，P.lugubris的标本进入凋落物的深层。这表明，使用P.lugubris叶凋落物作为越冬栖息地可能解释其与林地的密切联系，它的发生在更北的纬度相比，本属的其他成员。
Pardosa lugubris occurs in the vicinity of woodlands and overwinters among leaf litter. Field recordings of litter temperatures in winter indicate that temperatures within the litter fluctuate much less than those on the surface and that the lower the air temperature the greater the difference between the temperature of the surface litter and that of the deep litter. Specimens of P. lugubris, in a litter hill constructed in the laboratory, moved into the deeper layers of the litter as the temperature was lowered below freezing. It is suggested that the use P. lugubris makes of leaf litter as an overwintering habitat may account for its close association with woodland and its occurrence in more northerly latitudes compared with other members of the genus.
