Philaeus chrysops is a species of jumping spider (Salticidae).
Distribution and habitat[edit]
Philaeus chrysops occurs in the Palearctic, from Portugal to South China and Korea. They are rather common in most of Europe, especially in the southern countries. They are not reported in Ireland, Iceland and some other northern regions, like most of Scandinavia, Estonia, Latvia and Northern European Russia. Outside Europe, they are present in North Africa, the Near East, Turkey, the Caucasus, Central Asia, Iran, Afghanistan, China, Mongolia and Korea.[1][2][3]
Habitat[edit]
These spiders prefer open and warm areas. They can usually be found in dry, rocky or sandy habitats, with low and open vegetation.
Description[edit]

Normal body length is 7–12 millimetres (0.28–0.47 in), but 5 mm small males do occur. Unusual for spiders, the males are often bigger. The sexes differ extremely Sexual dimorphism: males are very colorful with a glaringly red opisthosoma (chrysops means "golden eye" in Greek). The males have a dark brown or blackish cephalothorax, usually with two broad longitudinal white stripes behind the rear eyes. The abdomen is bright orange-red on the back and the sides, with a longitudinal black stripe in the center and black shoulders. The long, slender legs are dark with the patellae and most of the tibiae of the first two pairs bright orange-red. [2]
The cephalothorax of the female is similar to the male, but with much smaller white stripes. The back of her abdomen is largely covered with a very broad rather irregular brown band with two longitudinal whitish stripes and a few whitish marks near the sides. The remainder of the abdomen and the sides may be orange-brown or pale brown, the legs light brown with dark brown rings.[1][2]
Biology[edit]
These spiders can be found in the warm spring and summer months. The young spiders become adults around July. Like the other jumping spiders, this species does not use the canvas to capture prey. Philaeus chrysops hunts freely, quickly jumping on prey and blocking it with claws and pedipalps. Hunting takes place only during the day, in the hot hours. [2] When the adult male has found a female, it will start a courtship, shaking forelegs in the air and drumming on the ground with the abdomen and pedipalps. After the mating, females lay the eggs in a cocoon, watching them until hatching. [2][4]
