Its from this research that we can determine that there are six main types of spider webs, with three addition types of webs that serve unique purposes. The females of the species are larger than the males and they may vary considerably in colour. There are [8], The silk of double-tailed tent spiders are also among those being studied for possible applications in creating nanocapsules and microcapsules.[16]. KELLY: They filmed the spiders deadlifting, so to speak, their prey and found one spider was able to use its silk engineering to lift a cockroach 50 times - five zero - heavier than itself. Numbers of eggs range from two to 1,000. "These were just the first insights in this direction," Greco said.

CORNISH: As for what exactly is going on, Greco studied this superpower in what's known as tangle-web spiders. How it works The function of these webs is very similar to cobwebs. Even in a single web, there are different types of silk (and glue) used to make frame lines, capture lines and anchor lines, she says. Some of the colonies were returned to their ancestral homes. She also reports on general science, covering climate change, paleontology, biology, and space. And a spider that rears the young might have to wait to eat until the hunters are sated, so it might go hungry. Their common name 'double-tailed tent spider' comes from the pair of blunt projections at the posterior end of their abdomens. The cephalothorax and legs are an orangish red color.

Pruitt and his co-author, Charles Goodnight, a biologist at the University of Vermont in Burlington, report that the experiment provides ample evidence for group selection. If the group, not the individual, is the most important basic evolutionary unit, then the group as a whole will evolve characteristics that are best suited to the environment, such as an intrinsic ratio of warriors to nannies.

Egg sacs come in a variety of different shapes, ranging from discs to perfect spheres. KELLY: In this way, the spiders can snag their prey at ground level and then slowly hoist them into the air, adding band after band of silk, which creates the necessary tension to lift the animal closer and closer. Though the social spiders present strong evidence for group-level selection in the wild, researchers arent sure if its a common occurrence in nature. Her videos about dinosaurs, astrophysics, biodiversity and evolution appear in museums and science centers worldwide, earning awards such as the CINE Golden Eagle and the Communicator Award of Excellence.
