De Gewone strekspin behoort tot de familie Strekspinnen, Tetragnathidae. Het mannetje meet tot 9 mm; het vrouwtje tot 12 mm. De spin heeft een zeer slank lichaam en lange poten en gifkaken. Het achterlijf is zilverwit met een paar gele of bruine gegolfde lijnen. Deze spin bouwt, net als de andere Strekspinnen, een wielweb met een gat in het centrum. De spin houdt zich meestal op een grashalm of plantenstengel op terwijl het eerste en tweede paar poten recht vooruit strekt en vierde paar achteruit strekt langs het achterlijf. Met het derde pootpaar klauwt ze zich vast. Door deze houding en door haar kleur is ze perfect gecamoufleerd. Het mannetje houdt bij de paring met zijn gifkaken de gifkaken van het vrouwtje in bedwang opdat hij zelf geen slachtoffer wordt van zijn gezellin.

Je kunt deze spin vinden van mei tot september op hoge grassen en riet op vochtige, onbeschaduwde plaatsen, vaak bij water.

==============================================

The little Long jawed Orb Weaver, Tetragnatha extensa is a member of the family Tetragnathidae. The male is 9 mm and the female is 12 mm in length. This spider spins its orb webs on grasses and other low vegetation especially in waterside and wetland habitats, both lowland and upland. As with other members of this genus, when disturbed the spider leaves its web and stretches out along a leaf with the four anterior legs pointing forwards and the four posterior legs pointing backwards. Its elongate shape, combined with this pose, enables the spider to escape detection by predators. Both sexes are mature from early to mid-summer and sometimes into the autumn.

You can find this spider from May to September on low growing vegetation, often near water or boggy areas.

Leucauge cf dromedaria Family Tetragnathidae

Orb-weaver spiders or araneids are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields and forests. "Orb" was previously used in English to mean "circular",[2] hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.[1]

 

The family is cosmopolitan, including many well-known large or brightly colored garden spiders. With around 3,100 species in 169 genera worldwide, Araneidae is the third-largest family of spiders (behind Salticidae and Linyphiidae).[1] Araneid webs are constructed in a stereotyped fashion. A framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets.

 

Orb-webs are also produced by members of other spider families. The large golden orb-weavers (Nephilidae) and the long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Araneoidea. The cribellate or hackled orb-weavers (Uloboridae) belong to a different group of spiders. Their webs are strikingly similar, but use a different kind of sticky silk.

Tiny, compact but very stylish....a Silver Camel spider (Leucauge dromedaria) female. Abdomen length approx' 10mm. These spiders build horizontal webs just above the ground, up to one metre in diameter. This one had constructed her web between a flower pot and bush in my garden.
