Arctosa perita · smėlyninis pasalūnas

They are native to Europe, North Africa, Turkey, the Caucasus, and Russia, however they have also been introduced into Canada. Arctosa perita spiders live on dry, sandy soils or coastal dunes, where they create their burrows. Adults are remarkably well camouflaged as they rest on sand, the many rings of the legs helping to break up their outline.

Mature Arctosa perita of both sexes have a body length of 6.5–9 mm, although males tend to be smaller. The carapace typically ranges from brown to grey, although it can also be black. Dark streaks radiate from the fovea, and white hairs form broken lateral bands towards posterior half of the carapace. The sternum is heart-shaped, and brownish-black in colour. The abdomen is brown, and paler towards the sides. It usually has a greyish cardiac mark, which is flanked on either side by a pair of pinkish-white patches with smaller, white spots behind. The pattern is repeated on the rear of the abdomen, on either side of a pale brown median band. The legs are robust, pale, with clear dark annulations and, along with the palps, are covered in setae and spines.
