Some time ago, I took my children to the lake to play. Because they often take them to observe animals, plants, insects, etc., the results have just gone for a while, and the two little ones have new discoveries. In the past, it turned out to be two beautiful big spiders who didn't know their names. Two nets juxtaposed in the yellow-rimmed grass, slender legs, and a beautiful yellow-and-black stripe on the abdomen, similar to the belly of a wasp. (And the babies guess whether it is a protective color, simulating a wasp to avoid being eaten by birds)

Because this spider is also the first time to see, do not know how to introduce to the baby, had to take a picture with the mobile phone, picture search, but the results are not correct. So the picture + text (yellow and black striped spider) searched together, and immediately saw the encyclopedia of the horizontal striped golden spider. Can be true, but also has a cute name, known as "can write English spider"; so with two little guys carefully observed, found that really can write, faintly visible English letters, v, w and other shapes;
A horizontally striped golden spider that can write English letters, faintly visible v w
While carefully observing the two spiders, Dabao said: That spider has dragonflies to eat, and this spider who can write has nothing to eat. Before we could finish speaking, a grasshopper just jumped on our feet. I grabbed it and told the babies, let's invite this writing spider to breakfast. By the way, you can also let the babies observe how the spiders prey on.
The striated golden spider, which could write, ate breakfast
The moment the grasshopper was thrown into the net, the horizontal striped golden spider quickly rushed over, unfolded the two front feet to manipulate the net around the grasshopper to wrap it, and quickly spit out a lot of silk threads to wrap it in layers. It was as if the little grasshopper had been covered with a quilt, and at the same time as the quilt was covered, the cobwebs had also broken a big hole. The whole action is too fast, originally the first to shoot the video result only took the second half of the screenshot, late time to upload the video for everyone;

Continuing to observe, it seems that this industrious little spider did not seem to eat the prey directly, but first went to repair the broken web, and then came back to lie on the prey. It is estimated that it is waiting for the venom to slowly liquefy the grasshopper and directly suck it.
Rhabdomy Golden Spider Small Popular Science:
The rhabdomy golden spider, argiope bruennichi (scopoli, 1772), known as the "English-speaking spider", is a silk-web spider distributed in central to northern Europe, North Africa and Parts of Asia. It is more common in mountainous areas or around the moat, but rarely in plain areas. It lives in sun-exposed grass and wet areas, and is generally netted on grass or in the field. It is a master of weaving nets, and the circular nets woven can sometimes reach a radius of up to 1.5 meters. The spit out spider silk resembles English letters, and the purpose is to enhance the reflex and attract prey to pounce on the net for easy catching.
Like other spiders of the genus Agaricus , they have prominent black-yellow markings on their abdomen. The color is quite vivid, I guess it is a mimetic protective color;
Rhabdomy Spider teaches math and English:
The transverse golden spider has 4 pairs of footlets, that is, 8 feet. Take your baby and count. If you increase the difficulty first, you can count how many circles there are in the spider web. By the way, you can also recognize the shape.
Take your child to take a closer look at what letters are written on the cobwebs.
Life habits of the rhabdomy golden spider
The rhymatized golden spider forms a web among long grass piles or bushes in the early morning or dusk, and it takes almost an hour to complete each time, and the web often has a letter-like structure. The conspicuous triangular shape on the web, called the "stabilizing ribbon", is located in the center of the cobweb.
After the prey is caught by the cobwebs, the rhabdomy golden spider will quickly wrap it in spider silk. When bitten, it is injected with toxins and proteolytic enzymes that paralyze the prey. It preys on some insects, including borer spiders, leafhoppers, planthoppers and other pests. (This time they ate dragonflies and grasshoppers.)
Rhabdomy golden spider mating pattern
The male rhabdom golden spider (5.5-5.9mm) is smaller than the female rhabdom golden spider (18-25mm), and the difference is a bit More. They often stay in or around the female's web, waiting for her to complete the final shelling and reach sexual maturity. At this time, the horns of the female spider will be soft for a while, and the male spider can mate without being bitten by the female spider.
Male striated golden spiders vary greatly in size than females
Spiders are not insects.
The basic characteristic of insects is that adults generally have two pairs of wings and three pairs of feet, while spiders belong to the arthropod phylum arachnids, which are "close relatives" to insects that also belong to the arthropod phylum insects. Spiders and crabs, shrimp, centipedes, etc. are arthropods.
Take your kids outdoors spider epilogue:
In the following articles, it was found that children are naturally interested in plants and animals and small insects. I'll rush you to explain this to them. The two little spider children observed for almost 2 hours, and then ate barbecue, played with leather balls, played for a while and would go back to see, and came to tell me if the little spider had eaten.
It seems that interest is a natural teacher, and outdoor nature is also a good teacher, which can teach children a lot of content. Come and join us in taking our kids outdoors.
