The jumping spiders, unlike the other families, have faces that are roughly rectangular surfaces perpendicular to their direction of motion. In effect this means that their forward-looking, anterior eyes are on "flat faces", as shown in the photographs. Their eye pattern is the clearest single identifying characteristic.
Phaeacius is a spider genus of the family Salticidae (jumping spiders), found in sub-tropical China and between India and the Malay Peninsula, including Sri Lanka, Sumatra and the Philippines. Although other spiders can jump, salticids including Phaeacius have significantly better vision than other spiders, and their main eyes are more acute in ...
a: ^ Jackson and Blest (1982) say, "The resolution of the receptor mosaic of Layer I in the central retina was estimated to be a visual angle of 2.4 arc min, corresponding to 0–12 mm at 20 cm in front of the spider, or 0–18 mm at 30 cm." b: ^ Several species of cursorial spiders drink nectar as an occasional supplement their diet, and juveniles of some orb-web spiders digest pollen while ...
Hogna wolf spider (family Lycosidae) showing the enlarged posterior median eyes typical of the family. The eyes of spiders vary significantly in their structure, arrangement, and function. They usually have eight, each being a simple eye with a single lens rather than multiple units as in the compound eyes of insects. The specific arrangement ...
Lohit Y.T, a specialist in rivers and wetlands from WWF India reached Nandi Hills near Bengaluru late one evening and trekked up to a popular sunset spot where he had spotted an tiny spider which seemed different as he had never seen any spider before with the black and white pattern and distinctly shorter jump pattern seen in Tenkana arkavathi from Nandi Hills.
The genera Lyssomanes, Chinoscopus, Hindumanes, and Sumakuru make up the Lyssomaninae, which is one of the six deeply-diverging subfamilies of jumping spiders. [4] They are long-legged, with translucent bodies frequently green or yellow. They resemble lynx spiders, except that they have large anterior median eyes. [citation needed]
Most species in the genus Maevia follow the mating behavior of the gray morph of the M inclemens species. [5] This courtship behavior pattern is standard for all jumping spiders which involves three phases [6] In the first phase, males will utilize a mating display to attract a female's attention for the latter to identify if the male is of her species.
Chalcoscirtus lepidus is a small spider. [9] The male has a brown carapace that is typically 1.06 mm (0.04 in) long and 0.69 mm (0.03 in) wide. It has a pattern of black veins and has a sparse covering of light elongated scales. The eye field is dark brown with the area around the eyes is black. The spider's face, clypeus, is yellow-brown and ...
