 The garden tent web spider belongs to the family of orb weaver spiders.  Although they are in the orb-weaver family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimeters long.  The spider constructs a tent web, about a meter high form the ground. Builds the web in an open environment. Prefers moist and thick surroundings. Hunting method -  The spider rests at the hub or in the retreat. An airborne insect striking the upper barrier web either drops onto the horizontal net or remains entangled in the upper barrier web. The prey produces vibrations in the web upon impact and/or during struggling, and these are transmitted via web elements to the hub. Some discrimination of prey characteristics on the basis ...

  The  Neoscona theisi are a species of spotted orb-weavers. The  females have a body length of up to 11 mm. Males are slightly smaller, measuring up to 9 mm.  They build an  orb web  and rest near the center.  Individuals vary in color from dark reddish-brown to pale-yellow with a distinct pattern on the upper abdomen, lighter along the center-line, and darker on the sides. The legs are light with dark patches at the joints.  They are found from  Cyprus, Israel, Russia, India, Philippines, China to Indonesia, Japan, Australia. They normally feed on smaller bugs, flies, and other insects. It is usually observed that they retreat back to long leaves to rest at noon.  According to me the spider in the above image is a female.
