Yellow garden spider vs Banded garden spider
These two are easy to mix up. Here's how to tell a yellow garden spider from a banded garden spider, and whether either one bites or stings.
Yellow garden spider
Argiope aurantia
Banded garden spider
Argiope trifasciata
≠The key differences
Argiope trifasciata has many thin crosswise silver, yellow and black bands on a more pointed abdomen; both occur in similar habitats, but A. aurantia has bolder, larger yellow-and-black patches.
A. aurantia is larger, with bold black and bright yellow patches rather than many thin bands, and usually builds a heavy zigzag stabilimentum; A. trifasciata has finer, more numerous bands and a more pointed abdomen.
