Trochosa ruricola is a wolf spider whose common name is rustic wolf spider. The females are 15 mm (0.6 in) but can reach 25 mm (1.0 in), and the males are 10 mm (0.4 in). Both sexes are dark brown and have a pale band that runs down to the carapace and continues to the abdomen. Their habitat is in grassland, woodland, scrub, and lawns that are in Asia, Europe, and North America. The spider hunts on the ground and often gets caught in pitfall traps. Females carry an egg sac around on their abdomen for around 3 weeks until spiderlings emerge and gather on the mother's back.
