Orb weavers or Orb-web spiders

Araneidae: Orb weavers or Orb-web spiders

This is a large family of large to small-sized
spiders. The araneid or typical orb-weaving spiders are distributed all over
the world. They are spinners of orb webs and are called “orb-weavers” or
“orb-web spiders”. Almost all the species construct orb-webs of various size,
complexity and inclination though most are vertical or near vertical; in the
heights above ground and also in houses, buildings, etc.; but they are not
foliage, either high upon the trees or in shrubs, herbs or grasses at various
ground dwellers. The orb-webs have geometrical precision and beauty. Many of
araneids having no retreats, merely run away from the web or drop to the ground
them build nest-like retreat by folding a leaf or bunch of leaves, a little
away from the web and directly connected with the web centre by threads. The
when disturbed. If undisturbed, they climb up to the webs by means of thread
consisting of many concentric rings and series of radii, which
they pulled out while falling. Generally the male araneids are much smaller
than the females and are not commonly seen in the webs unlike females. To
characteristically hang down from the centre of the web. Some araneids are
capture prey, these spiders construct highly specialized vertical orb webs,
in daytime with a few exceptions as the tropical Argiope, Cyclosa, Gasteracantha, etc.
Usually after every few days found to construct silk stabilimentum in the centre of the web.
Since the araneid spiders are nocturnal in habit, they are not seen in the web
the sticky silk dries up or becomes torn and is replaced and repaired in the
evening by the spiders. Some spiders roll up their webs in the morning before
leaving the webs to take shelter under bark or retreat or leaves. Again, the
araneids devour all sorts of arthropods that are entangled in their webs. Since
web is reconstructed in the evening for trapping the prey at night. The
and tension of threads of the web. Then they quickly turn their preys with legs
these spiders have poor vision, they locate their prey by feeling the vibration
victim. The prey is bitten before being dragged to the hub or to the retreat,
and simultaneously the fourth legs pull out silk from spinnerets and wrap the
where prey is sucked. Inedible objects are cut out of web and dropped to the
ground.
