Ecologyedit
Like other species of the same genus, it is known as a "signature spider"; it builds a web with a zig-zag stabilimentum somewhat resembling letters. The mature female of A. anasuja always rests at the centre of the orb with her head facing downwards. The orb has an opening at the centre and when disturbed she goes through the hole and exits on the other side of the plane of the web.[2]

Female
With egg sac
They are commonly found on flora of Mimosaceae family. They prefer to make the web in a plane of shadow in the daylight.[citation needed]
Reproductionedit
Male is smaller than female. Male spins a web around the female's web, which is known as a companion web. After the mating, as in other common spiders, female kill the male. Female lay eggs on the companion web and wrap them up into a sac. Spiderlings eat each other in the sac until the strongest spiderling break the sac wall.[3] The sac can hold from 400 to 1,400 eggs.[4]
