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.
Arctosa virgo
Arctosa virgo is a species of wolf spider in the family Lycosidae, described by Chamberlin in 1925. It is known from the United States, with records from oak-hickory forests in southern Missouri. As a member of the genus Arctosa, it belongs to a group of cursorial wolf spiders adapted to ground-dwelling predation. Very little specific information has been published about this species beyond its original description and a few collection records.
