Philaeus chrysops is a species of jumping spider (Salticidae).
Phidippus audax, the bold jumper or bold jumping spider, is a common species of spider belonging to the genus Phidippus, a group of jumping spiders easily identified by their large eyes and their iridescent chelicerae. Like all jumping spiders, they have excellent stereoscopic vision that aids them in stalking prey and facilitates visual communication with potential mates during courting. Bold jumping spiders are native to North America and have been introduced to Hawaii, Nicobar Islands, Azores, and the Netherlands. They are typically black with a distinct white triangle on their abdomen.
Phidippus regius, known commonly as the regal jumper, is a species of jumping spider in eastern North America.
Zygiella x-notata, sometimes known as the missing sector orb weaver or the silver-sided sector spider, is a spider species in the family Araneidae. They are solitary spiders, residing in daily-spun orb webs. Z. x-notata is a member of the genus Zygiella, the orb-weaving spiders. The adult female is easily recognized by the characteristic leaf-like mark on her posterior opisthosoma, caudal to the yellow-brown cephalothorax.
Phryganoporus candidus, also known as the foliage web spider, is a small, subsocial jumping spider endemic to Australia. On average, they are 6–10 mm long and are a mottled brown colour, covered in silvery grey hair. They typically reside in arid and semi-arid locations, building their nests in various trees, bushes, and other plant-life. They have a mutualistic relationship with Acacia ligulata, and therefore prefer to build their nests in these trees.
Phidippus johnsoni, the red-backed jumping spider or Johnson jumping spider, is one of the largest and most commonly encountered jumping spiders of western North America. It is not to be confused with the unrelated and highly venomous redback spider.
Nephila pilipes is a species of golden orb-web spider. It resides all over countries in East and Southeast Asia as well as Oceania. It is commonly found in primary and secondary forests and gardens. Females are large and grow to a body size of 30–50 mm, with males growing to 5–6 mm. It is the second largest of the orb-weaving spiders apart from the recently discovered Nephila komaci. The first, second, and fourth pairs of legs of juvenile females have dense hairy brushes, but these brushes disappear as the spider matures.
Phidippus octopunctatus is a jumping spider that occurs in the United States and Mexico, mostly in the Great Basin Desert. It is among the largest jumping spiders found in North America, approaching 25 millimetres (0.98 in) in body length. They are gray to brownish-gray in color.
Cosmophasis umbratica is a species of jumping spider found in South and Southeast Asia. They are members of the family Salticidae and the genus Cosmophasis. They are commonly spotted on green vegetation. C. umbratica shows extreme dimorphism when viewed under UV light: males reflect UV on all body parts that are displayed during intraspecific interaction, while females and juveniles do not reflect UV at all. It seems that C. umbratica uses this in sexual signaling. A similar phenomenon is found in some butterflies. For example, several species of Colias and Gonepteryx, both of the family Pieridae, also display sexual signaling.
Amaurobius ferox, sometimes known as the black lace-weaver, is a common nocturnal spider belonging to the family Amaurobiidae and genus Amaurobius. Its genus includes the permanently social species A. socialis, and three subsocial species, A. fenestralis, A. similis and A. ferox, all three of which have highly developed subsocial organizations.
Phidippus otiosus is a species of jumping spider that is found in southeastern North America. It is primarily a tree-living species. Females reach a body length of about 16 mm. Its iridescent chelicerae can range in color from purple to green.
Maevia inclemens or the Dimorphic Jumping Spider is a relatively common and colorful jumping spider of North America. In the males there are two forms, a very rare phenomenon in zoology. These use different courting displays, and differ in appearance: the "tufted" morph has a black body and pedipalps ("palps"), three black tufts across its "head", and pale legs; and the "gray" morph has black and white stripes all over its body and legs, orange palps, and no tufts. However, each form accounts for 50% of the adult males, and they are equally successful in mating. A female of Maevia inclemens is 6.5 to 8.0 millimetres long, while males are 4.75 to 6.50 millimetres long.
Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats. Adult spiders measure between 3 and 4.5 mm in length. The cephalothorax and abdomen are bronze to black in color, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae and front femora. Like many jumping spiders, Z. sexpunctatus males exhibit ritualized courtship and agonistic behavior.
Rugathodes sexpunctatus is a minute species of spider in the family Theridiidae, the cobweb or tangle-web spiders. This family includes the medically important genus Latrodectus—the widow spiders. The species in the genus Rugathodes are too small to be dangerous to humans. Very little is known about most species in this genus.
Phidippus Clarus, also known as the Brilliant Jumping Spider, is a species of jumping spider found in old fields throughout eastern North America. It often waits upside down near the top of a plant, which may be useful for detecting prey, and then quickly jumps down before the prey can escape. The spider is one of 60 species in the genus Phidippus, and one of about 5,000 in the Salticidae, a family that accounts for about 10% of all spider species. P. clarus is a predator, mostly consuming insects, other spiders, and other terrestrial arthropods.
Hogna carolinensis, commonly known as the Carolina wolf spider and giant wolf spider, is found across North America. It is the largest of the wolf spiders in North America, typically measuring at 18–20 mm for males and 22–35 mm for females.
Anelosimus jabaquara is a species of spider found in subtropical, humid, lowland forests in Brazil. Anelosimus jabaquara was first described by Herbert W. Levi in 1956. These spiders cooperate to spin and repair the colonial web, capture prey, and care for the brood. Colony size is small, and the sex ratio is biased towards females.
Schizocosa ocreata is a species of wolf spider in the family Lycosidae that is found in North America. The Schizocosa ocreata is a spider that is most commonly known as the “brush-legged wolf spider” because of their distinct dark-colored fur-like coverings around their legs. The S. ocreata are commonly found in North American states, usually in the middle and eastern United States.
Phidippus apacheanus is a species of jumping spider in the family Salticidae. It is found in the United States, Mexico, and Cuba.
Latrodectus revivensis, also known as the desert widow, is a species of venomous spider belonging to the Latrodectus genus and located in the Negev desert and the Arava valley (Arabah).
