Arctosa alpigena
Hilltop Wolf Spider
Arctosa alpigena is a wolf spider in the family Lycosidae with a holarctic distribution spanning North America, Greenland, and Eurasia. It is one of numerous Arctosa species adapted to open, often sandy or gravelly habitats. Like other wolf spiders, it is an active ground-dwelling hunter rather than a web-builder. The species has been subject to reproductive biology studies examining spatial and temporal patterns of mating and offspring production.
