In people's minds, spider webs can generally catch small flying insects or insects such as flies and mosquitoes. Spider web trapped a "big guy" - Fei Yan, have you ever seen it? Recently, a video of a spider web catching swallows appeared on the Internet, and in the video, a small swallow was entangled in the spider web, unable to get out, and finally successfully rescued by the photographer, which made netizens call "magic".
On the 5th, the reporter contacted the photographer of the video - Yang Gongli, a teacher at the primary school in the center of Lianhua Town, Wangkui County. He told reporters that at about 10 o'clock on the 3rd, he stood in the courtyard of the science popularization base outside the central primary school and heard the rapid call of a bird, which seemed to be a cry that the bird was afraid to make after being frightened. Teacher Yang quickly followed the sound and found a small swallow in the courtyard aisle that was entangled in a spider web, and his body was struggling hard, but he couldn't break free of this web.
This spider web is woven between the clothesline and the tree, very hidden, after the swallow hits the net and is trapped, the web line is wrapped around the swallow's wings, the more it struggles, the tighter it is, like a "dead knot", unable to get out.
"A small spider web can stick swallows, but it's really powerful!" Even Yang Gongli, who was teaching science classes, was shocked by the scene in front of him, he quickly took out his mobile phone to shoot a video, and then went forward to carefully dispose of the web lines on the swallow, he felt that these spider web lines were very tough and sticky. The trapped little swallow was rescued, and Yang Gongli released it on the spot.
The 57-year-old teacher Yang Gongli teaches science class at Lianhua Town Center Primary School in Wangkui County, and the children were also curious after hearing about this and came to the teacher to watch the video. Teacher Yang is also ready to give the children a good lecture on these animal knowledge and stimulate their interest in learning.
Later, Teacher Yang searched carefully in the courtyard and found two similar spider webs. Careful observation found that this spider web type is very large, elastic, the web line is thick and sticky, but I did not see what spider woven the web.
Why are swallows trapped by spider webs? What kind of spider "masterpiece" would this web be? The reporter interviewed relevant experts. Professor Xu Qing of the School of Wildlife Resources and Nature Reserves of Northeast Forestry University explained that from the video provided by the photographer, this swallow should be a newly fledged young bird, and the flight ability is not strong, so there will be a special case of "accidentally bumping" into the spider web and being trapped. Because he has just learned to fly, his physical strength is small, and he cannot break the net to save himself after being entangled. And the one who laid this "heavenly net" is likely to be a garden spider.
Garden spiders
Carnivores, predators with cobwebs, large nets, more regular structure, nearly round wheel shape, so also known as "round web spiders", it is first woven with inelastic spider silk into a web frame, and then with elastic spider silk woven into a concentric spiral web, the center of the web has no holes.
Garden spider has four pairs of foot, the appendages are highly poisonous, the body length can reach up to 6 cm, the most common in the courtyard is the large-bellied garden spider, the body is strong, usually in the evening in front of the eaves, between the branches, the corners of the wall and other places to open the net, and then hide in the dark place to wait for the insect to touch the net after predatoring.
