In most tropical countries, you might see a common animal called a black and yellow spider. Its other names are corn, writing, and garden spider. As the name suggests, the two colors dominate its body.
You might usually see this beautiful creature in late summer and make it a nice object of photography. Some scientists and biologists also have the interest to learn about this spider!
What about you? To know more regarding its life, description, diets, hunting methods, and other facts, you can read more information in this article.
Appearance and Description
In terms of shape and size, females are bigger. Still, they have several similarities. For example, both males and females have an egg-shaped abdomen. This area has a mark of yellow and black color.
Both female and male spiders build webs. It has a zigzag structure and white sticky design located in the midst of it. Some experts call it the stablementum! As the name suggests, it functions to stabilize the web.
Places to Live (Habitat)
The black and yellow spider has several favorite places to live. For instance, they choose open fields near vegetation and higher bush. Some of them also dwell in eaves, gardens, buildings, and houses.
For the information, this spider loves to live in an area with little wind. If possible, they choose habitats with no wind at all. Besides, they prefer sunny areas to shady or dark locations.
Unlike hunter spiders, they would build webs and wait for prey. The size of these webs vary, which can reach up to 2 feet in diameter. As for the height, the webs are about 5 inches above the ground.
Black and Yellow Spider’s Behavior
It is fun to watch this beautiful creature’s behavior in the wild. When building webs, the males often choose a location near to the females. However, its size is usually smaller than the females’.
In terms of design, the male’s webs have a vertical and z-shaped line amid the web. Another difference is mobility. Males often leave their webs to roam. Meanwhile, the females stay patiently at home.
When detecting nearby predators, these spiders would hide well in the nearest plants or bushes. Not to mention, they react well to available threats out there.
Their Favorite Diets
Here is an interesting fact. They eat some parts of their web each day. Later, they replace it with fresh silk. According to experts, those web parts are nutritious and help the spiders to get a small amount of energy.
The black and yellow spider is indeed carnivorous. Moreover, they can eat prey with a bigger size than theirs. Despite the fact, they still choose smaller prey rather than the big ones.
As for the primary diets, these spiders eat various flying insects. These include flies, wasps, grasshoppers, bees, and aphids. They are not aggressive and active, though.
Instead, they stay still while waiting for prey to be stuck in their beautiful sticky web. To paralyze the target, they inject venom, wrap them with silk, and create a sac. Next, they will eat it comfortably.
Mating and Reproduction
They do breeding once in a year. The females can amazingly produce thousands of eggs. They place the egg sacs amid the web and protect it well from any threats.
The mothers would guide these eggs until she dies. At the first beginning of the winter, female spiders are no longer alive, while males die soon after mating, mostly because the females eat them.
Later, in the early spring, the babies start to come out from the eggs. Their size is tiny, and they decide to either stay in webs or move around along with the wind.
Enemies or Predators
Just because they are carnivorous, it does not mean they can live peacefully without predators. Their biggest threats are lizards, birds, shrews, and humans.
So, is there anything they can do aside from hiding? These spiders will bite if harassed. Fortunately, the venom is deadly to small creatures but harmless to humans.
When harassed and threatened, they also perform a unique defense mechanism by vibrating their web. The purpose is to create an illusion. By doing so, their size will seem bigger than it is.
You can easily find this beautiful spider in nearby gardens, especially during summer. Even though they are not deadly to humans, their venom may be stingy and hurtful. So, be careful around them.
They tend to build webs and wait for prey instead of chasing around their target. Their web is strong, big, and beautiful. You can distinguish the female from male spiders by looking at the design of the web.
As for the foods, the black and yellow spider is fond of flying insects trapped by the webs. Well, what do you think about them? They are such interesting animals to learn, right?
