Yes they do. Although they don't spin a 'classic' web, they do trail silk as they walk so they can always find their way. Tarantulas that occupy burrows also lay 'trip lines' of silk outside so they know when potential prey is approaching.
Setae
Tarantulas do not capture their prey by using webs. They use their silk to make egg sacs, to line burrows, or (of they are arboreal) to make something like an inverted silken sock that they rest or sleep in.
they are called setae.
well, catapillars dont really spin silk, silk worms make silk. catapillars make a sort of spider string but only when they cacoon themselfs up.
Silkworms spin silk, the answers in the name.
Spiders spin webs with their silk and also use it to wrap up their prey.
one silk worm can only spin about .5 of an in and sometimes more. in fact, a large one can spin enough to be wrapped around the tips of your fingers. It takes the silk almost forever to spin just that little so just think about how many silk worms they would need to make a silk dress! But, because China and Japan had so many of them. Other countries wanted this, so China traded silk during 300 BC on the Silk road.
They make silk...when the spin their cacoon
Spin webs, crawl, eat, mate, and die like every other arachnid.
Silk is not made out of silk worms. Silk is made by silk worms which spin to make a cocoon for themselves.
they spin it out of a cocoon then theyweave it in to chlothes
Unlike most spiders, tarantulas do not catch their prey in webs. They find a spot, and just sit and wait. When something appears, they use a burst of speed to grab the victim with it's eight legs, and then inject immobilizing venom.Most tarantulas are 'ambush' predators. Instead of roaming the area looking for prey, they'll sit extremely still and simply wait for prey to come within range. They 'launch' themselves at the intended victim, and quickly inject powerful venom.
