How do spiders build webs?
Answers:
Some spiders spin funnel-shaped webs, others make sheet webs, spiders like the black widow make tangled, maze-like, webs, and still others make the spiral "orb" webs that are most commonly associated with spiders. These webs may be made with sticky capture silk, or with "fluffy" capture silk, depending on the type of spider. Webs may be in a vertical plane (most orb webs), a horizontal plane (sheet webs), or at any angle in between. Most commonly found in the sheet-web spider families, some webs will have loose, irregular tangles of silk above them. These tangled obstacle courses serve to disorient and knock down flying insects, making them more vulnerable to being trapped on the web below. They may also help to protect the spider from aerial predators such as birds and wasps.
By spinning in every direction and leaving tacky stuff as they go!
they get lots of mates in and surf the web
(harvestmen). The study of spiders is known as arachnology.
All spiders produce silk, a thin, strong protein strand extruded by the spider from spinnerets most commonly found on the end of the abdomen. Many species use it to trap insects in webs, although there are many species that hunt freely. Silk can be used to aid in climbing, form smooth walls for burrows, build egg sacs, wrap prey, and temporarily hold sperm, among other applications.
They use a silk that is released from their abdomen and they let the wind catch it and wait for it to attach to something, they then quickly spin their web with very fine silk until structurally safe, they then retrace beginning of the first strand and replace this with a stronger silk thread and they eat the finer silk thread until the whole web is finished. Obviously it depends on the spider but it normally takes about an hour.
spiders build webs to catch their prey.their saliva is a sticky viscous liquid that dries into a very fine thread.they salivate and spin webs.
