Yellow garden spiders grow in large sizes, but are not toxic to humans. Advanced builds ball-shaped nets and most of them make stabilizers which are zigzag-shaped lines in nets made of thicker bands.

This species spends more time in stationary and sits in the middle of the net with its head down to wait for insects to be entangled in fine silk thread. Unlike other spider species that prefer solitary life, A. appensa can live proudly with their colleagues.
