What kind of spider is this? Black and white stripes, super flat body.

Arachnida, Arachnida, including 4 genera 189 species. This kind of spider can't weave a web, and often wanders between trees and branches in hilly areas. This species is distributed in the northern mountainous areas, and often inhabits bark or corners to catch small insects. Female spiders have the behavior of protecting eggs.

The ability of pseudoplaneta;

1, free fall

For years, Yanoviak and his colleagues have been looking for insects that can glide accurately. In order to find such insects, the researchers used a simple test to judge: throwing small creatures from a very high place.

The "airdrop test" shows that many ants can "slide" and fly like immature mantis and grasshopper. However, when the research team first tested spiders, it ended in failure.

Finally, the scientists chose the giant spider Paragnathus for testing. Some subspecies of Paragnathus live in tropical America. Although Okumo can be as big as a can lid, its thickness is less than five cents, and some are even thinner.

2. Skills like cats

Next, the research team sprinkled fluorescent powder on the spider to better identify it and prevent it from sticking to the inner wall of the container and not pouring it out.

Then, scientists conducted experiments in the rainforests of Peru and Panama respectively: dropping spiders from a height of 20 to 25 meters above the ground.

Experiments show that spiders are more flexible than cats. After being poured out of the container by scientists, the spider instantly adjusted its posture and slid head-down to a nearby tree trunk.

3. amazing gliding ability

Some scientists who were not involved in this research were also surprised that spiders could glide.

Sarah Cruise is an independent biologist and an expert on spiders. She said that she was "convinced" of the research results-spiders can also fly like insects, but in different ways.

"For spiders, this result is really amazing." Marie Herberstein, a behavioral ecologist at Macquarie University in Australia and editor of Spider Behavior, said, "Spiders usually use silk as a safety rope to prevent falling." She said.
