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.

Overview
Orb-weaver spiders 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. The English word orb can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Description
Generally, orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the center, making a "Y". The rest of the scaffolding follows with many radii of nonsticky silk being constructed before …
Taxonomy
The oldest known true orb-weaver is Mesozygiella dunlopi, from the Lower Cretaceous. Several fossils provide direct evidence that the three major orb-weaving families, namely Araneidae, Tetragnathidae and Uloboridae, had evolved by this time, about 140 million years ago. They probably originated during the Jurassic (200 to 140 million years ago). Based on new molecular evi…
Reproduction
Araneid species either mate at the central hub of the web, where the male slowly traverses the web, trying not to get eaten, and when reaching the hub, mounts the female; or the male constructs a mating thread inside or outside the web to attract the female via vibratory courtship, and if successful, mating occurs on the thread.
In the cannibalistic and polyandrous orb-web spider Argiope bruennichi, the much smaller males ar…
