Argiope submaronica is a species of spider in the family Araneidae (orb-weavers), found from Mexico to Bolivia, and in Brazil.

The name was at one time considered a synonym of Argiope argentata, but A. submaronica is now treated as a separate species.

[2] This was the first recorded phenomenon of an emballonurid bat being preyed on by an invertebrate, and the first documented proof of Argiope being able to catch and consume a mammal.

A. savignyi sometimes spins a silk disc, sometimes a cruciate pattern, and sometimes combines both types.

These structures are thought to provide five purposes: protection from predators, advertising to vertebrates to avoid web damage, prey attraction, web stability, and a source of shade.
