Saitis barbipes is a European- Mediterranean frequently encountered spider from the family of the jumping spiders (Salticidae).
features
The animals reach a body length of five to six millimeters. The males are strikingly colorful and have a greatly enlarged and densely haired third pair of legs. It is laterally flattened and laterally colored coral red up to and including the metatarsus . There are black hair fringes on the upper and lower edges, which become increasingly thick up to the metatarsus. The tarsus is densely hairy white. The other pairs of legs are pale yellowish and curled blackish. The prosoma is dark brown and hairy white-gray above the eye field. The front eyes are bright emerald green, behind them there is a red to orange colored horizontal stripe, which extends on the sides to the rear pair of eyes. The opisthosoma is marked on the upper side with a whitish vertical stripe, which is bordered brown and black on the sides. The females are inconspicuously yellow-brown in color. Your eye field is dark. The upper side of the opisthosoma is provided with a longitudinal band which is darkly bordered on the side, in the rear area of which there are several dark angular spots. The legs are light brown and almost without drawing.
Way of life
Saitis barbipes occupied throughout their range about the same habitats as in Central Europe , the zebra spider ( Salticus scenicus ). When disturbed, the males raise the noticeable third pair of legs to confuse the opponent. During courtship, the males wave the greatly enlarged pair of legs to attract the female's attention. Sexually mature animals can be found all year round.
