Why Doesn't a Spider
Get Stuck to its Own Web?
an age old question and I'm sure you'd like an answer,
well here goes:
Have you ever wondered why insects stick to a spider's
web but the spider doesn't? Some spiders have two or
three claws at the tip of each leg. In web-weaving
spiders, one of these claws has a special area that is
used for hooking on to the strands of the web. The spider
can use this special claw to swing from strand to strand
without having to touch the sticky part of the web. In
this way, a spider can move quickly over its web without
Most webs are made of at least two types of silk, the
anchor silk (that the spider uses to move around on)
and the sticky snare silk (that insects get stuck on).
Just in case the spider slips, it has a special oily
substance that helps to stop it getting stuck in its own
Even though every spider makes some kind of silk, not
all the types of silk are the same. There are at least
six or seven kinds of silk glands found in spiders, and
each gland makes its own kind of silk.
Different silks are used for web-building, wrapping
food, or for encasing an egg sac. Spider silk may or may
not be sticky, depending on whether or not it is being
used to catch food.
