All About Yellow Garden Spider

March 14th, 2012 · No Comments

The flashy spiders, crawling across tall weeds, gardens and bushes in your garden are the yellow garden spiders. These yellow garden spiders are found on almost all the sunny areas and gardens around United States. They are usually spotted around late summer and early fall. They are generally referred to as yellow and black spiders or black and yellow garden spiders. The yellow garden spider belongs to the group of spiders called the orb weavers. 

Yellow Garden Spider Physical Characteristics
The female yellow garden spider is about 19 to 28 millimeters in size. Silver hair cover the carapace of the female spider. She has eight eyes that are procurved with lateral four eyes. These four eyes are nearly joined and present on the two projections present on either side of the carapace. The front legs are mostly black in color. The second, third and fourth pair of legs are black in color with yellow or red femora. She has an elongated oval abdomen that is pointed on the rear end. There is a distinct yellow and black pattern on her abdomen. There are two anterior humps on the female body. The male yellow garden spider is just 5 to 8 millimeters in size, and its legs are lighter in color than the female legs. The male spider has a similar patterned yellow and black body.

Yellow Garden Spider Range and Habitat
Black and yellow garden spider is found all over United States. However, it is commonly found in the coastal regions of America. It is found in the eastern half of North America, Ontario and the Atlantic provinces in Canada. The yellow garden spider habitat consists of sheltered areas between tall vegetation, eaves of houses, etc. that are protected from wind. 

Yellow Garden Spider Web
The best way to identify a yellow and black spider is through his web. These spiders are known for their web that is made up of dry spokes supporting spiral thread of adhesive silk. There are free zones that separate the hub from the spirals. During the day, the spider rests in his web head down. At night, the spider rests over the hub with a conspicuous zigzag band of bright white silk called the stabilimentum. You can read more about identifying spider.

Yellow Garden Spider Feeding Habits
Yellow garden spider is a friendly creepy crawly that will eat away the critters around the garden. Female garden spider can hunt prey larger than her own size. These large prey’s include grasshoppers, aphids, katydids, cicadas, June beetles, moths, wasps, bees and other insects. These spiders also eat up aphids, flies, ants, etc.

Yellow Garden Spider Reproduction
The yellow garden spider tends to breed just once a year. The males keep roaming around in search of a female. Once they find their damsel, they build a small web near her web. They begin courting the female by plucking strands of her web. A male will always approach a female with a safety drop line ready. This is because he never knows, what tics her off and she attacks him. Once he is successful in mating the female, he dies. The female will probably eat up her dead mate. 

After mating, the female lays her eggs at night on a silky sheet. Then these eggs are covered with another layer of silk and a third brown layer of silk. She will create a ball of the sheets using her legs. This ball is called egg sac that is about 5/8″ to 1″ in diameter. This egg sac is suspended on her web near the hub or center of the web. One female spider can produce 1 to 4 egg sacs containing over 1000 eggs each. She guards them as long as she can and dies during the first hard frost. The young yellow garden spiders are born around spring. They are so small in size they resemble dust particles and are blown away to different areas by the wind.

Yellow Garden Spider Bite

Now, is a yellow garden spider poisonous? One would definitely ask this question, especially after having a look at the flashy color. It does contain some amount of venom that is used to subdue the prey. However, as humans are obviously not the targeted prey for these spiders, the venom does not cause much harm. One is most likely to suffer from female yellow garden spider bite. This happens especially if she feels threatened, while protecting her egg sac. If a yellow garden spider does bite an unfortunate human, it will just lead to a brief stinging sensation. One may probably develop a slightly raised, red bump that may remain for 2 to 4 days. You can read a bit about spider bite symptoms and treatment.

This was all about the yellow garden spider. It will remain an inconspicuous guest in your garden, hardly causing any trouble. If you spot one on your morning walk in a nature trail or garden, leave it alone. It will not cause much harm and mind its own business, when left alone.
