Natural history. The webs of this species were found at the edges of water bodies and have the same basic structure described for A. lagotis and A. castaneus. It is made of a horizontal sheet of irregular silk forming a funnel, leading to a retreat of dense silk, which opens at the base (Berg, 1883; Carbajal 1983). Berg (1883) describes insects, spiders and tadpoles as prey, hunted in the web or directly on the water surface, where these spiders can run quickly. The eggsac is spherical and greyish-green, with a white equatorial seam (Bachmann, personal comm. in Carbajal 1983).
