What are some interesting facts about spiders?
Fun Cross Spider Facts: 1 Cross orbweavers typically hang upside down at the center (hub) if their web. Eric Eaton describes their behavior when alarmed, “The spiders themselves will literally shake at the close approach of a person or other large animal, vibrating their web and no doubt startling the inquisitive visitor. Should that tactic fail, most orb weavers drop abruptly from their web, anchoring a dragline to the hub so that they can climb back up once danger passes” (Bug Eric http://bugeric.blogspot.com/2011/08/spider-sunday-cross-spider.html ). 2 Cross orbweavers are one of the best-known spiders in the world and in 2010 had the honor of being named “European Spider of the Year.” 3 Eric Eaton also tells us that ““Anita” and “Arabella” were two female Cross spiders that were sent into space in Skylab 3 in 1973 to study the effects of zero gravity on web construction.” 4 Cross orbweavers are not aggressive and generally bite only if cornered or inadvertently grabbed. Side effects of their bites are mild in most people (redness, swelling, pain) and last only a few days.

There are several white or yellow spots within and around the folium. Four elongated spots appear toward the anterior end of the abdomen, creating what appears to be a cross. As with the banded garden spider, the carapace has three dark longitudinal lines or bands.

Where Can They Be Found?
The cross orb-weaver spider, also known as 'araneus diadematus', 'the common garden spider' or 'diadem spider' is one of many orb-weaver spider varieties.
Size And Coloration
Mature, adult females are significantly larger than the males (which is the case in almost all spider species), and tend to grow between 6.5 and 20 millimetres, whereas males are usually between 5.5 and 13 millimetres.
Lifespan
The average lifespan of a cross orb-weaver is thought to be just 12 months, although experts say this is hard to gauge due to the fact that so many are killed or eaten within this time by birds, cats and other spiders. On the very rare occasion that a human does get bitten by this species, it is because the spider was provoked.
Breeding
Females lay between 300 and 900 eggs in late September, and they usually lay these in safe, sheltered areas of gardens, such as between rocks, between cracks and crevices in garden walls and underneath dead tree bark. The eggs are tiny and are all enclosed in a hemisphere-shaped cocoon made of fine silk threads which are a pale yellow in colour.
Some Interesting Facts
Interestingly, most cross orb-weavers eat their webs every night (they have been observed doing this and it normally takes them just a matter of minutes), they are thought to do this so that they are able to eat any smaller insects that have gotten stuck on the silk threads of the web, and also to protect themselves.

When do spiders mate?
Mating occurs in summer-autumn The male spider is much smaller than the female and unassumingly marked. When it is time to mate, he spins a companion web alongside the females. After mating, the female lays her eggs, placing her egg sac into the web. The sac contains between 400 and 1,400 eggs. These eggs hatch in autumn, however, the spiderlings overwinter in the sac and emerge during the spring. The egg sac is composed of multiple layers of silk and designed to protect its contents from damage; however, many species of insects have been observed to parasite the egg sacs.
