Pardosa lapidicina
Stone Spider
Pardosa lapidicina, commonly known as the stone spider, is a small wolf spider in the family Lycosidae. It inhabits cobble beaches and rocky shorelines near water, particularly above the tide line. The species exhibits distinctive migration patterns tied to tidal cycles and seasonal temperature changes. Research has documented its use of sit-and-wait foraging behavior combined with sun-basking, and its diet includes small arthropods such as dipterans, collembolans, and amphipods. Males recognize females through a contact sex pheromone located on the female's carapace and legs, requiring physical contact for detection.
