Nursery web spider

Spider ( Pisaura mirabilis )

The predatory spiders ( Pisauridae ) include 336 species in 53 genera; the most species-rich genus Dolomedes. The related with the wolf spiders prey spiders are mainly distributed in tropical and subtropical areas. In Central Europe, only three species of the family are to be found: The hunting spider Dolomedes fimbriatus Ndete Gera, Dolomedes plantarius and the cunning spider Pisaura mirabilis. A term appearing in the catalog by Norman Platnick by Simon in 1937 described fourth type Dolomedes on was clercki in the revision of Franz Renner clearly synonymized with that already described in 1757 by Clerck kind Dolomedes plantarius, is therefore not a separate kind of prey spiders, typical behaviors of the superfamily of Lycosoidea.

Etymology

Pisauridae usually called predatory spiders ( eg Bellmann 1997) and hunting spiders ( Schaefer 1971, Heimer and Nentwig 1991, Platen et al., 1995). In English they are called web spiders nursery, nursery web weavers, wolf spiders big, fisher spiders ( Gertsch 1979, and others) or Pisaurids ( Bristowe 1971), in French Les Pisaurids (Simon 1898) or Pisauridae ( Millot 1968, Hubert 1979 ) in Dutch Grote wolf spiders (van Katwijk 1976) or Kraamwebspinnen ( Roberts 1998).

The term hunting spiders avoids the syllable " robbery", which gives no sense in contrast to birds of prey. However, this term can lead to confusion, since it is used also for other families, such as the giant crab spiders. On the other hand Pisauriden are ecologically not hunters, but build fishing and residential networks. The juvenile stages of native species that are hunters as adults, ie for prey in the herb layer or at the waters edge lurking, living in small networks. Since only some species as adults inhabit the shores and there usually Eliminating prey from the water surface and rarely fish (ie, tadpoles and fish catch ), fishing spiders is also unsuitable as a family name. Rainar Nitzsche calls after the English model nursery web spider.
