Did You Know Spider don't Stuck on their Web?
Have you ever observed a spider web? You may have been shocked by how sticky it had been.Spiders are neither bugs nor insects. All Insects have three body parts: the head, the thorax with wings and six legs, and the abdomen. Spiders are Arachnids and have two body parts: the cephalothorax (head + thorax) with eight legs, and the abdomen.
Why do spiders spin webs and why are spider webs so sticky?
When a spider is hungry, it heads to the web. Spiders who weave webs are used to catch flies and other insects and small animals that they eat for food.
When a spider catches prey inside the sticky strands of its net, it approaches the unfree insect and uses its fangs to inject venom. The venom either kills or paralyzes the prey, permitting the spider to relish its dinner in peace.
It takes about one hour for the common spider to construct an elaborate web of silk thread, called a spider web.
Did you ever wonder why spiders aren't getting stuck in their webs?
Unlike unsuspecting prey, spiders don't get contact with their webs all right away.
Some people mistakenly believe that spiders have oily legs that stop them from sticking out to their webs. This is not true, because spiders do not have oil glands.
Spiders of the genus Argyrodes are kleptoparasites that steal prey from other web spiders. Recent studies have shown that in addition to stealing prey, they occasionally eat the silk of the host spider webs.
Spiders Walk on Their Tiptoes:
Watch a spider traverse its web and you'll notice it takes careful steps, tiptoeing delicately from thread to thread. Only the tips of every leg make contact with the silk. This minimizes the probabilities of the spider becoming ensnared in its own trap.
If you observe a spider at length, you will see her pull each leg through her mouth, gently scraping off any silk bits and other debris that inadvertently stuck to her claws or bristles.
Where do the spiders take rest?
Not all webs are sticky throughout, either. Many spiders only build threads with adhesive “glue" in certain elements of their webs. Different areas, especially where the spider may rest, are built without “glue" to make it easier for the spider to move around the net.
Do spiders groom themselves?
To avoid sticky things, spiders also groom themselves very carefully. Spiders habitually clean their legs of all pieces of silk and different dust which can cause them to get stuck on their webs.
