Habronattus americanus is a species of jumping spiders from the family Salticidae.
The female spider is brown and gray, with a small color range. [1] The male spider is black colored from top, and the male's pedipalp is red, along with parts of the legs. [2] The red color is used to attract female mates with courtship displays. [3]
This species lives in western North America, ranging from British Columbia, Canada, in the north to California, United States, in the south. It ranges from the coast into Alberta and Montana. [4] It may reach further, but current knowledge is based only on reported sightings.
Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems. Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large.
The American toad is a common species of toad found throughout Canada and the eastern United States. It is divided into three subspecies: the eastern American toad, the dwarf American toad and the rare Hudson Bay toad. Recent taxonomic treatments place this species in the genus Anaxyrus instead of Bufo.
Nicrophorus americanus, also known as the American burying beetle or giant carrion beetle, is a critically endangered species of beetle endemic to North America. It belongs to the order Coleoptera and the family Silphidae. The carrion beetle in North America is carnivorous, feeds on carrion and requires carrion to breed. It is also a member of one of the few genera of beetle to exhibit parental care. The decline of the American burying beetle has been attributed to habitat loss, alteration, and degradation, and they now occur in less than 10% of their historic range.
Trichonephila clavipes, commonly known as the golden silk orb-weaver, golden silk spider, or colloquially banana spider, is an orb-weaving spider species which inhabits forests and wooded areas ranging from the southern US to Argentina. It is indigenous to both continental North and South America. Known for the golden color of their silk, the large size of their females, and their distinctive red-brown and yellow coloring, T. clavipes construct large, asymmetrical circular webs attached to trees and low shrubs in woods to catch small- and medium-size flying prey, mostly insects. They are excellent web-builders, producing and utilizing seven different types of silk, and they subdue their prey by injecting them with venom, as opposed to related species which immobilize their prey by wrapping them in silk first. They are not known to be aggressive towards humans, only biting out of self-defense if touched, and their relatively harmless venom has a low toxicity, posing little health concern to healthy human adults. Due to their prevalence in forests, T. clavipes may be encountered by hikers.
Habronattus is a genus in the family Salticidae. Most species are native to North America. They are commonly referred to as paradise spiders due to their colorful courtship ornaments and complex dances, similar to birds-of-paradise. Males display intricate coloration, while females are cryptic.
Phidippus audax, the Bold jumper or Daring 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.
Misumena vatia is a species of crab spider with a holarctic distribution. In North America, it is called the goldenrod crab spider or flower (crab) spider, as it is commonly found hunting in goldenrod sprays and milkweed plants. They are called crab spiders because of their unique ability to walk sideways as well as forwards and backwards. Both males and females of this species progress through several molts before reaching their adult sizes, though females must molt more to reach their larger size. Females can grow up to 10 mm (0.39 in) while males are quite small, reaching 5 mm (0.20 in) at most. Misumena vatia are usually yellow or white or a pattern of these two colors. They may also present with pale green or pink instead of yellow, again, in a pattern with white. They have the ability to change between these colors based on their surroundings through the molting process. They have a complex visual system, with eight eyes, that they rely on for prey capture and for their color-changing abilities. Sometimes, if Misumena vatia consumes colored prey, the spider itself will take on that color.
Evarcha culicivora is a species of jumping spider found only around Lake Victoria in Kenya and Uganda. At maturity, E. culicivora spiders have an average size of 5 mm for both males and females. The range in size for either sex is quite small, with females being only slightly larger on average.
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.
Habronattus viridipes is a species of jumping spider that can be found in the eastern United States and southern Canada.
Habronattus borealis is a species of jumping spiders from the family Salticidae, found in Canada and the United States.
Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders. Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
Lyssomanes viridis, commonly known as the magnolia green jumper, is a species of jumping spider of the genus Lyssomanes, for which it is the type species. The species' native range extends through much of North America and Central America.
Habronattus pyrrithrix is a species of jumping spider in the family Salticidae. It is found in the southwestern United States and western Mexico.
Habronattus cognatus is a species of jumping spider. It is found in North America.
Habronattus mataxus is a species of jumping spider found in Texas and northern Mexico.
Habronattus mexicanus is a species of jumping spider in the genus Habronattus. The species was first identified in 1896 in Mexico, after which it is named, originally allocated to the genus Habrocestum. The species has subsequently been identified in locations in North and Central America, as well as islands in the Caribbean Sea. The spider is small, but displays one of the most complex sexual displays, including sophisticated vibatory song patterns.
Habronattus orbus is a species of jumping spider in the family Salticidae. It is found in the United States.
Habronattus texanus is a species of jumping spider in the family Salticidae. It is found in the United States and Mexico.
Habronattus dossenus is a species of jumping spider. It is found in Mexico and the southwestern United States. They are most well known for their unique dynamic signals such as scraping, thumping, buzzing, and/or buzzing. It has been shown that there is a strong correlation between their seismic (vibration) signals and motion signals, suggesting that H. dossenus utilize inter-signal interactions to create integrative communication. These seismic signals can range from rapid phasic sounds that are less than 200 milliseconds long to long phrases lasting multiple seconds.
