Zoropsis spinimana is a spider species belonging to the family Zoropsidae.
Males of Z. spinimana reach a length around 10–12 mm (0.39–0.47 in), while females are 15–18 mm (0.59–0.71 in) long. This spider resembles a wolf spider, as its eyes are of the same configuration, but unlike wolf spiders, the eyes of Zoropsis spiders are more spread out along the front third of the cephalothorax. The front body (prosoma) is brownish with broad darker markings. The abdomen (opisthosoma) has median black markings. The legs are mainly a speckled brown color.
The abdominal black marking evokes the vampire of the 1922 German silent film Nosferatu , which led to the common German name of the spider, Nosferatu-Spinne. [1]
Zoropsis spinimana is distributed widely in the Mediterranean, but reaches into Russia, and was introduced to the United States, primarily in the San Francisco Bay Area, [2] [3] [4] and the United Kingdom, primarily the London area. [5]
Since the mid-1990s, the species has been sighted along Europe's North-South transport routes, like Lucerne, Basel, Freiburg im Breisgau, Duisburg and Innsbruck. It is not clear why the relatively large spider was not found there earlier, as Mediterranean holidays with mobile homes were popular in the 1970s, and would have provided the spiders with many suitable habitats and transport opportunities. Ecologists assume that climate change enabled the spiders to take hold and reproduce north of the Alps. [6] Recent finds presumably near the Northern border of the current distribution range include a 2023 find in Copenhagen. [7]
Spiders of the species can be found on forest edges under rocks and tree bark, where they hunt for prey during the night. Like all zoropsid spiders, Z. spinimana does not build a web, but hunts freely. Since this spider cannot survive in a harsh climate, it often seeks refuge in human habitation and is frequently found in houses where the temperature is milder and food is more abundant.
Spiders of this species are sexually mature in autumn. The females lay eggs in spring, resting in a brood chamber on the cocoon.
The Mediterranean recluse spider is a species of spider that originated in the Mediterranean region as its name implies, but can now be found in many parts of the world and is listed as one of the most invasive spiders worldwide. Usually dwelling in caves, the spiders will also inhabit basements and tunnels. Their webs shelter their egg sacs, which hatch into young that molt as they grow. The spider hunts at night and eats species including silverfish and cockroaches, and they usually target smaller insects.
The spider species Tegenaria domestica, commonly known as the barn funnel weaver in North America and the domestic house spider in Europe, is a member of the funnel-web family Agelenidae.
Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider, banana huntsman spider or cane spider.
The zebra spider is a common jumping spider of the Northern Hemisphere. Their common name refers to their vivid black-and-white colouration, whilst their scientific name derives from Salticus from the Latin for “jump”, and the Greek scenicus, translating to “theatrical” or “of a decorative place,” in reference to the flashy, zebra-like coloration of the species.
The woodlouse spider is a species of spider that preys primarily upon woodlice. Other common names refer to variations on the common name of its prey, including woodlouse hunter, sowbug hunter, sowbug killer, pillbug hunter and slater spider.
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.
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.
The Kauaʻi cave wolf spider, also known to local residents as the blind spider, is only known to occur in a few caves in a lava flow with an area of 10.5 km2 (4.1 sq mi) in the Kōloa–Poʻipū region of Kauaʻi, Hawaiian Islands, and only six populations are known to exist. While their nearest surface-dwelling relatives have large eyes, this species has completely lost its eyes. They reach a body length around 20 mm (0.8 in), and are reddish brown and completely harmless to people. Unlike most wolf spiders, it produces only 15 to 30 eggs per clutch. The female carries the egg sac in her mouthparts until the spiderlings hatch.
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.
Misumenoides formosipes is a species of crab spiders (Thomisidae), belonging to the genus Misumenoides. The species' unofficial common name is white banded crab spider, which refers to a white line that runs through the plane of their eyes. This species is a sit-and-wait predator that captures pollinators as they visit the inflorescences on which the spider sits. The spider has strong front legs which are used to seize prey. The female spider is much larger than the male. The pattern of markings on females is variable and the overall color of the body can change between white and yellow dependent on the color of their surroundings. The color pattern for males, which does not change in their lifetime, differs from females in that the four front legs of males are darker and the abdomen is gold. The spider can be found throughout the United States. Males search for sedentary females within a heterogeneous habitat and guard them until they are sexually mature to reproduce.
Plexippus paykulli is a species of jumping spider. It is native to south east Asia but has spread to other parts of the world and globe. In the United States it is called the pantropical jumping spider. It is usually associated with buildings and may be found near light sources catching insects attracted by the light. It is named in honor of Gustaf von Paykull.
Synema globosum is a species of spiders belonging to the family Thomisidae. It is sometimes called the Napoleon spider, because of a supposed resemblance of the markings on the abdomen to a silhouette of Napoleon wearing his iconic hat.
Trogloraptor is a genus of large spiders found in the caves of southwestern Oregon. It is the sole genus in the family Trogloraptoridae, and includes only one species, Trogloraptor marchingtoni. These spiders are predominantly yellow-brown in color with a maximum leg span of 3 in (7.6 cm). They are remarkable for having hook-like claws on the raptorial last segments of their legs.
Pardosa amentata, otherwise known as the wolf spider or spotted wolf spider is a species of spider in the genus Pardosa belonging to the family of wolf spiders, Lycosidae. The species has a widespread distribution in central Europe and northwestern Europe and are commonly found on the British Isles. The species hunts its prey on the ground rather than weaving a web.
Progradungula otwayensis, commonly known as the odd-clawed spider, is a species of cribellate spider endemic to the Great Otway National Park of Victoria, Australia. It is one of only two species in the gradungulid genus Progradungula.
Tigrosa helluo is a species of spider belonging to the family Lycosidae, also known as wolf spiders. T. helluo was formerly known as Hogna helluo before differences between dorsal color patterns, habitat preferences, body structures, etc. were discovered. The species is native to the United States, Canada, and Mexico. It can be found across the eastern half of the United States, primarily in the Northeast and New England, and as far west as Nebraska and Kansas. T. helluo can be found in diverse habitats including woods, marshes, fields, and riparian areas. Typically, members of this species prefer to live in wetter areas as opposed to dry environments. Males tend to live for around a year and females will live for close to two years.
Zora silvestris is a prowling spider in the family Miturgidae which is found in Europe and Central Asia.
Hasarinella distincta is a species of jumping spider in the genus Hasarinella that lives in South Africa. The species was first described in 2013 by Charles R. Haddad and Wanda Wesołowska. With a dark brown oval cephalothorax] that is between 3.4 and 3.8 mm long and a brown ovoid abdomen that has a length between 3.7 and 4.5 mm. The male has a marking of three white streaks, one in the middle and two along the edges, on the carapace. The female does not. It is the copulatory organs that enable the species to be differentiated from the related Hasarinella berlandi, particularly the wider seminal ducts in the female and the oval palpal bulb in the male. It lives in both grassland and woodland.
Plexippus fuscus is a species of jumping spider in the genus Plexippus that lives in Guinea. It was first described in 2002 by Christine Rollard and Wanda Wesołowska. Only the female has been described. It is a medium-sized spider, with a dark brown carapace typically 3.4 mm (0.13 in) long and a reddish-brown abdomen that is 2.3 mm (0.091 in) long. Both the carapace and abdomen are covered in dark brown hairs. The abdomen has a yellow marking like a belt. Although superficially similar to other species in the genus like Plexippus paykulli, it can be distinguished by the presence of a long thin pocket in the epigyne and significant sclerotisation on the edges of the copulatory openings, which are also wider than other Plexippus spiders.
Badumna longinqua or the grey house spider is a species of spiders in the family Desidae. Native to eastern Australia, it has been introduced into New Zealand, Japan, the United States, Mexico, and Uruguay.
