Macracantha hasselti
These spiders are active during the day, and are often seen sitting in the center of their webs or maintaining them. They build their webs in open areas to catch flying insects, which they trap in their sticky orb webs. When an insect touches the web, the spider quickly rushes in and begins spinning and wrapping the insect in more webbing to keep it trapped. The web acts like an air filter, trapping weak-flying insects that cannot see the fine silk. Most orb webs are rebuilt every day, and the web may be up only during the day or only at night. - Bali Wildlife
