Lynx spider (Oxyopidae) is a family of araneomorph spiders first described by Tamerlan Thorell in 1870. [1] Most species make little use of webs, instead spending their lives as hunting spiders on plants. Many species frequent flowers in particular, ambushing pollinators, much as crab spiders do. They tend to tolerate members of their own species more than most spiders do, and at least one species has been identified as exhibiting social behaviour. [2]

Description

There are several genera of Oxyopidae and they differ in their habits and adaptations. Most of them have large spiny bristles on their legs and in many species the bristles form almost a basket-like structure that may assist in confining the prey that they grasp, and protect the spider from its struggles. Most Oxyopes and Hamataliwa species are small to medium in size. Lynx spiders, in spite of being largely ambush hunters, are very speedy runners and leapers, alert and with good vision. Oxyopidae in general rely on keen eyesight in stalking, chasing, or ambushing prey, and also in avoiding enemies.

Identification

As with many other families of spiders, the arrangement of their eyes is typical of the family and is an important aid in identifying them as members of the family. Six of the eight eyes of Oxyopid spiders are arranged in a hexagon-like pattern, more or less on a prominent hump on the front upper corner of the prosoma. The other two eyes are smaller, less conspicuous, and generally are situated in front of and below the other six. The basal parts of the chelicerae of most species are large, vertical and parallel, which combine with the bluff front end, a "high forehead" to the prosoma, to give most species a peculiar "flat-faced" appearance.

Hunting

They tend to be drab ambush hunters, depending to some extent on the season, some occupy flowers, ambushing pollinating insects. In this they resemble the crab spiders ( Thomisidae ) in behaviour. Others crouch in wait, camouflaged on plant stalks or bark. Peucetia species on the other hand, commonly are larger. They are rangy and their camouflage is vivid green, adapted to hunting or hiding among foliage.

Behavior

Except when defending egg purses, many tend to flee rapidly when approached by predators or large creatures such as humans. They tend not to be very aggressive towards other members of their own species, and sometimes meet casually in small groups. Possibly as an extreme example, at least one member of the genus Tapinillus is remarkable as being one of the few social spiders, living in colonies with communal feeding, cooperative brood care, and generational overlap. [3] Peucetia viridans is unusual among spiders in that females defending their egg purses will spray or "spit" venom at intruders, including humans. [4]

Benefits

Some members of the genus Oxyopes are abundant enough to be important in agricultural systems as biological control agents. This is especially true of the striped lynx spider ( Oxyopes salticus ). Their net value in agriculture has been disputed however, on the grounds of their predation of pollinators. [5]

Genera

Genera common in the United States include common lynx spiders and green lynx spiders. As of April 2019, the World Spider Catalog accepts the following genera: [6]

The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders.

<span class="mw-page-title-main">Jumping spider</span> Family of spiders

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.

<span class="mw-page-title-main">Huntsman spider</span> Family of spiders (Sparassidae)

Huntsman spiders, members of the family Sparassidae, are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places. In southern Africa the genus Palystes are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related.

<span class="mw-page-title-main">Ctenizidae</span> Family of spiders

Ctenizidae is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiidae. The name comes from the distinctive behavior of the spiders to construct trapdoors, and ambush prey from beneath them.

The Palpimanoidea or palpimanoids, also known as assassin spiders, are a group of araneomorph spiders, originally treated as a superfamily. As with many such groups, its circumscription has varied. As of September 2018, the following five families were included:

<i>Peucetia</i> Genus of spiders

Peucetia is a genus of lynx spiders that is found worldwide.

<i>Peucetia viridans</i> Species of spider

Peucetia viridans, the green lynx spider, is a bright-green lynx spider usually found on green plants. It is the largest North American species in the family Oxyopidae. This spider is common in the southern U.S., Mexico, Central America, and in many West Indies islands, especially Jamaica. Lynx spiders are hunters specialized for living on plants. This species does not use a web to capture its prey. It pounces on its prey in a cat-like manner, which is the reason for the name lynx. It is active during the day.

A social spider is a spider species whose individuals form relatively long-lasting aggregations. Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies.

<span class="mw-page-title-main">Tarantula</span> Family of spiders

Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.

<i>Oxyopes salticus</i> Species of spider

Oxyopes salticus is a species of lynx spider, commonly known as the striped lynx spider, first described by Hentz in 1845. Its habitat tends to be grasses and leafy vegetation; grassy, weedy fields, and row crops.

<i>Oxyopes lineatus</i> Species of spider

Oxyopes lineatus is a species of spider in the family Oxyopidae, the so-called lynx spiders.

<i>Hamadruas</i> Genus of spiders

Hamadruas is a genus of Asian lynx spiders that was first described by Christa Laetitia Deeleman-Reinhold in 2009.

Leticia Avilés is an Ecuadoran evolutionary biologist and ecologist who studies the evolution of social behavior and the evolution of life history traits in metapopulations. Her methods include a combination of theory and empirical work, the latter using social spiders as a model system. Her research on these organisms has addressed questions such as why some spiders live in groups, why do they exhibit highly female-biased sex ratios, and why have they evolved a system where individuals remain in the natal nest to mate from generation to generation.

<i>Oxyopes</i> Genus of spiders

Oxyopes is a genus of lynx spiders found worldwide. It includes arounds 300 species and is classified under the lynx spider family Oxyopidae. Like other lynx spiders, they are easily recognizable by the six larger eyes arranged hexagonally on top of the head (prosoma), with the remaining smaller two eyes in front. They are also characterized by long spine-like bristles (setae) on their legs. They are ambush predators, actively hunting prey by sight. Though they produce and use silk, they do not build webs to capture prey.

<i>Oxyopes heterophthalmus</i> Species of spider

Oxyopes heterophthalmus is a lynx spider from the family Oxyopidae, it is the type species of the genus Oxyopes and was described by Pierre André Latreille in 1804, it has a Palearctic distribution.
