Orb web spiders or orb-weavers

Family Araneidae

Home <--

Cyclosa conica with a prey in her wheel web

The Araneidae is a large family with more than 2500 species worldwide. In Europe 25 genera with 185 species are known.

Almost all these spiders make orb webs that are big in relation to the spider. The webs are denser in the center.

The genera Cyclosa and Argiope construct some sort of stabilizer in the center of the web.

The most famous spider in this family is the Araneus diadematus. Also called cross-spider, kruisspin, Kreuzspinne or Epeire diademe.

Although the name Araneidae is now preferred, in much of the older literature these spiders are called Argiopidae.

The Argiope is the 'Wow' spider in Europe. Argiope bruennichi Is a beautiful black, yellow and white striped spider that makes a zigzag in the center of its web.

Genus Araneus

Araneus is probably one of the most spotted spiders because of their size, which varies between 8 and 20 mm, and their large webs. Especially during autumn these spiders become large and you may walk in their webs they construct during the morning. Also in the morning their webs are seen when the sun illuminates them, often full with dewdrops.

Courtship can be hazardous for the small male. The female makes her yellowish
cocoon with 300 - 800 eggs in autumn and she dies. The eggs will hatch in May.
The young spiders are yellow with are dark patch on the abdomen.

If the web is damaged by wind and rain or by the large amount of caught prey, silk of the web is eaten by the spider to conserve protein. Only the foundation lines are
left and new radii and capturing spirals are constructed. Some of the orb weavers
use their web for longer periods and replace only part, usually one half, of
their web at one time.

The Araneus species varies a lot in color and markings.

Because the spider is big and vivid, it is one of the most studied spiders. You can find them everywhere, but especially outside your window. (Probably they like TV watching as much as you do.)

Araneus diadematus female and male	Araneus diadematus can vary a lot in colouring and appearance.

Genus Aculepeira

Of the two European species, only Aculepeira ceropegia occurs in the north. Their size varies between 12 and 15 mm.

The spider lives in bushes and low vegetation. They have a catching orb web and a hiding web.
Aculepeira ceropegia´s common name is "oak leaf" spiders. The pattern on their back resembles an oak leaf.

Genus Agalenatea

Agalenatea redii is the single European member of this genus. The male spider is between 3.5 and 4.5 mm, the female 5.5 - 7 mm.

It has an almost circular body and can be identified by the v-sign at the front end of the abdomen. This spider is very variable in color.

Genus Araniella


Araniella cucurbitina female in web Araniella cucurbitina is similar to A. alpica (below) The red dot on the spinnerets is characteristic for this spider. Their size varies between 4 - 11 mm.

Genus Argiope

More on this page

This is very beautiful spider a lot of people spot in their garden. As noted before the spider is not dangerous. The spider is easily recognized by the zigzag formation of white silk, which they weave in their web. Often it is a zigzag line through the center of the web or even a white cross of web material in which the spider is hanging.

It was thought that the zigzag of silk was made to strengthen the web but some neat experiments have shown that its function is to advertise the presence of their web to birds allowing them to avoid the web. Because the spider eats its old web before constructing a new one, destruction of the web by birds will lead to substantial protein loss. There is also a theory that suggests that the zigzag of silk attract insects because it reflects the ultra-violet radiation like flowers do.

Argiope bruennichi

Argiope bruennichi (youngster) or wasp spider.

This spider is about 20 mm in length. She makes her orb-web in long grass near the ground. The adult females have beautiful black, white and yellow markings.

The egg-sacs are large brown flask shaped and she hangs them in the web and guards until they hatch. She dies after the hatching of her eggs. The female often consumes the much smaller male after mating.

Genus Atea



Atea sturmi	Atea sturmi
This spider lives on conifers and bushes and has a size of 3 -5 mm. She resembles Atea triguttata the other species in this genus.

Genus Cyclosa Two strange looking spider can be found in this genus, Cyclosa conica and Cyclosa oculata. The size of these spiders varies between 3 - 6 mm. Marking and colour varies widely of the common occuring Cyclosa conica. The abdomen of the female has a tubercle that is rudimetary with the males. Cyclosa occulata has six tubercles in front, middle and end of the abdomen The large webs of these spiders are remarkable, often with a string of dirt/debris in it. The spider hides and lays her eggs in this camouflage. Cyclosa likes sunny places in bushes and low vegetation.

Genus Cercidia

The only species in this genus and characterised by its oval, in front pointed, abdomen. The spider makes it web without a centre just above the ground in which its waits for prey. When disturbed she rapidly falls to the ground. Its size varies between 3 and 4 mm.

Genus Gibbaranea

Four species occur in NW-Europe and their size varies between 4 and 7 mm. In both sexes the abdomen has a pair of extremeties on the front half of the abdomen.

They can be found on trees and bushes. Male and female are similar in apprearance .

Genus Larinioides

All these spiders spin orb webs close to water.

The Larinioides sclopetarius tends to live on man-made steel objects and is seldom found on vegetation.

I found this spider in the dunes on a steel lock. The spider can be black and white but there are also brown variants.

	Only one species, Mangora acalypha, can be found in our regions. The size of the spider is between 2.5 and 4 mm. The spider spins it web almost horizontal on bushes and low vegetation. The web is not very large but contains up to 60 radii.

Genus Zilla

Zilla diodia is only European member with a size of 2 - 5 mm. She prefer to make her web in the shade on bushes and heather. The spiders does not has a retreat but stays in the center of her web waiting for prey.

The male is identical to the female

Genus Zygiella

Zygiella x-notata can be found in the neighbourhood of houses. In winter,
it is the only orb web spider that continues to make webs.
Zygiella atrica is browner and is found away from houses on bushes or rocky sites.

This genus makes a orb web that misses two sectors. Through the middle of these two missing sectors a signal thread runs to the spiders hiding place.

Males can reach a length of 5 mm and the females 7 mm.
