Nursery web spiders (Pisauridae) is a family of araneomorph spiders first described by Eugène Simon in 1890. They resemble wolf spiders (Lycosidae) except for several key differences. Wolf spiders have two very prominent eyes in addition to the other six, while a nursery web spider's eyes are all about the same size. Additionally, female nursery web spiders carry their egg sacs with their jaws and pedipalps instead of attaching them to their spinnerets as wolf spiders do. When the eggs are about to hatch, a female spider builds a nursery "tent", places her egg sac inside, and stands guard outside, hence the family's common name. Like the wolf spiders, however, the nursery web spiders are roaming hunters that don't use webs for catching prey. They have a wide variety of prey, and larger species may prey upon vertebrates, particularly amphibians and fish.
Dolomedes is a genus of large spiders of the family Pisauridae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all Dolomedes species are semiaquatic, with the exception of the tree-dwelling D. albineus of the southeastern United States. Many species have a striking pale stripe down each side of the body.
The raft spider, scientific name Dolomedes fimbriatus, is a large semi-aquatic spider of the family Pisauridae found throughout north-western and central Europe. It is one of only two species of the genus Dolomedes found in Europe, the other being the slightly larger Dolomedesplantarius which is endangered in the UK.
Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms which is reflected in their large diversity of behavior.
Dolomedes minor is a spider in the family Pisauridae that is indigenous to New Zealand, where it is known as the nursery web spider.
The great raft spider or fen raft spider is a European species of spider in the family Pisauridae. Like other Dolomedes spiders, it is semiaquatic, hunting its prey on the surface of water. It occurs mainly in neutral to alkaline, unpolluted water of fens and grazing marsh.
Dolomedes aquaticus is a fishing spider that lives and hunts along the gravel banks of unforested New Zealand rivers. It prefers open riverbanks where it lives under rocks, usually less than 5 metres from the river. Its colouring allows it to blend in with river stones. Normally nocturnal, it sits and waits for its prey after dark, and can survive for short periods under the water.
Dolomedes tenebrosus or dark fishing spider is a fishing spider found in the USA and Canada.
Dolomedes scriptus is a fishing spider found in the United States and Canada, known as the striped fishing spider. Female spiders can grow to be over 6 cm in legspan. The spider is a pale brown colour with lighter stripes around its legs and a stripe down each side of the body. It is similar to D. tenebrosus.
The six-spotted fishing spider, Dolomedes triton, is an arachnid from the nursery web spider family Pisauridae. This species is from the genus Dolomedes, or the fishing spiders. Found in wetland habitats throughout North America, these spiders are usually seen scampering along the surface of ponds and other bodies of water. They are also referred to as dock spiders because they can sometimes be witnessed quickly vanishing through the cracks of boat docks. D. triton gets its scientific name from the Greek mythological god Triton, who is the messenger of the big sea and the son of Poseidon.
New Zealand has 1134 described spider species, with an estimated total fauna of 2000 species. Over 90 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions.
Dolomedes sulfureus is a species of spiders commonly known as fishing spiders belonging to the genus Dolomedes. They produce a venom that contains a group of neurotoxic peptides. The species is found in Russia, China, Korea, and Japan.
Dolomedes briangreenei is a species of fishing spiders found in Australia. The species name honours the physicist Brian Greene.
Dolomedes schauinslandi or the Rangatira spider is a large spider of the family Pisauridae. It is only found on South East Island (Rangatira), Houruakopara and Mangere Islands in the Chatham Islands, New Zealand. It is one of New Zealand's largest and rarest spiders.
Dolomedes gertschi is a species of nursery web spider in the family Pisauridae. It is found in the United States.
Dolomedes okefinokensis is a species of nursery web spider in the family Pisauridae. It is found in the United States.
Mantispa styriaca, the Styrian praying lacewing, is a species of predatory mantidfly native to Europe. It is a yellow-brown insect as an adult and has multiple larval stages.
Dolomedes dondalei is a species of large fishing spider endemic to the main islands of New Zealand. It is a nocturnal hunter, feeling the water surface for vibrations, and catches insects and even small fishes – the only New Zealand Dolomedes species able to do so.
Dolomedes facetus, commonly known as clever fishing spider, is a species of medium to large-sized fishing spider, which is endemic to Australia, where it lives in freshwater ponds and waterways in the coastal areas, ranging from Western Australia to Tasmania. It is common in northern parts of Australia, particularly Queensland and the Northern Territory.
Dolomedes venmani is a species of araneomorph spider in the family Pisauridae.
