No, not all spiders spin webs. Yes, you heard that right. All spiders have the ability to produce silk but only some of them use them for the construction of the web. Spiders generally web to build an egg sack to protect its eggs. While there are some spiders who use the web to catch or trap prey. Some spiders don’t use silk for web construction but they use silk to climb on smooth vertical surfaces, to wrap their prey, to run on them in an open chase, to drink water, to build egg sack, and many other.
Most spiders spin webs of one sort or another but only some use the web to entangle their prey.
The trapdoor spiders from tropical and subtropical countries are spiders that spin a tubular web in a hole in the ground. The hole the spider digs may be several inches deep and about an inch across. The web is spun to line the hole and once this is done the spider constructs a hinged trapdoor to fit the opening exactly. This is made from silk and small soil particles and is very often camouflaged with moss. This well-made retreat is a perfect home for the spider. If disturbed by its enemies it simply hangs on to the underside of the trapdoor, preventing from opening. It is not fully known how the trapdoor spider catches its prey. It is thought that is peers out from the hole with the trapdoor ajar and drags insects back into the hole as they pass by.
The spider webs are categorized based on the weaving style. Some of the web types are Tangle webs, Funnel webs, Spiral orb webs, Tubular webs, and Sheet webs.
