Template:Short description Template:Automatic taxobox

Alopecosa is a spider genus in the family Lycosidae (wolf spiders), with about 160 species. They have a largely Eurasian distribution, although some species are found in North Africa and North America.

Life cycle

Most species grow up to 2 cm. Alopecosa females make a burrow in which they deposit their egg sac. The female then stays in the burrow guarding the sac until the eggs hatch.Script error: No such module "Unsubst".

Taxonomy

Alopecosa inquilina

The species in this genus have been traditionally grouped into sibling species complexes (groups) based on morphological characters, but, as morphology-based taxonomy can be unreliable, alternative methods have also been employed to identify species correctly. For example, differences in observed courtship and copulation behaviour have proved to be a useful tool for species identification and delimitation, particularly in cryptic species.[1] Molecular techniques have also been applied to reconstruct phylogenetic relationships between some species.[1]

  • Alopecosa reimoseri (Kolosváry, 1934)
  • Alopecosa strandi (Roșca, 1936)

Distribution and habitat

The genus has a cosmopolitan distribution. The majority of species are native to Eurasia, although some species occur in Africa, and others are found in North and South America.[2] Alopecosa fabrilis is a critically endangered species found in Britain, with examples rediscovered in 2020 in the south of the country.[3] They favor dry climates.Script error: No such module "Unsubst".
