Spider Photos -  Star Bellied Orbweaver

Here's some photos of those common Garden spiders from the Orb Weaving family.   My apologies if there are some Araneus on pages where they don't belong but they are very hard to classify. Try this page for a species guide:
http://bugguide.net/node/view/1972/bgpage
Orb weavers (Araneidae) are often brightly coloured with rounded abdomens, some with peculiarly angled humps or spines. However, there is considerable variation in size, colour and shape in this group. They are often recognized for building beautiful, large, round webs, on which they rest, head downward, waiting for prey. The webs consist of a number of radiating threads crossed by two spirals. The inner spiral begins in the centre, winds outward, and is made of smooth threads like the radiating threads. It covers only the central 1/3 of the web. The outer spiral begins at the edges and winds inward. It is made of more elastic, sticky threads, coated with a liquid substance. One of the largest and most commonly encountered members of this group is Argiope aurantia, the yellow garden spider and we have photos of them on their own page. Garden Orb Weavers are NOT dangerous (but can bite as can most spiders) and rid your garden of many unwanted insects. They only live for one season and die off as Winter approaches, leaving their egg sacs behind to hatch out next Spring. Please select a section below.

ORB WEAVERS/GARDEN SPIDERS

Orb weavers (Araneidae) are often brightly coloured with rounded abdomens, some with peculiarly angled humps or spines. However, there is considerable variation in size, colour and shape in this group. There are only 5 types of spiders in this species. Large webs spun between cotton rows often are made by the star-bellied orb weaver, frequently the most abundant web-spinner in cotton and a beneficial predator of the many insects that destroy cotton. When the web is found, the spider may be located under a leaf to which one of the foundation lines of the web has been attached. One of its legs touches the line to alert the spider when prey is caught in the web. Identification is relatively simple because of the characteristic star-shape of the abdomen formed by a series of cone-like bumps (protuberances). The spider is brown with a white spot on the anterior portion of the abdomen. Adults reach a length of about 3/8 inch. Adults and immature spiders differ only in size. Numbers generally increase as the season progresses, reaching a peak in August and September when large numbers of immature spiders cover the countryside. The density of these spiders in cotton fields averages about one per 10 metres of row but peaks at one per 2 metres. The star-bellied orb weaver does not hunt its prey but waits for prey to get caught in its web. Thus, it is likely that most of its prey fly or jump into the web. Adult fleahoppers, bollworm-budworm moths, bigeyed bugs, pirate bugs, damsel bugs and honeybees are frequent prey of this spider. There is no evidence that this spider feeds on bollworm or budworm eggs under field conditions, but it may consume one small larva every 2 days.

STAR BELLIED ORB WEAVERS Acanthepeira

Hi, I found this unusual nocturnal spider last night in Theresa Park Pretoria. Please can you identify it for me?

Hi Glen, I photographed this little Orb Weaver while it was working the other night. These Orb Weavers are all over the place from late June through first frost in my area. Feel free to use the pictures if you want. --Damy

Hi Glen, I was taking a walk in the woods yesterday and almost ran into this extreme booby-trap. An Orb Weaver had its web spun between some very thorny Blackberry branches. So it was a double threat! Anyway, I avoided being bitten or snagged, and painstakingly took these 6 photos. I'm still a photo noob, so I had to place my hand behind the spider to get my camera to focus on it. Feel free to use the photos if you want. --Damy
