Eustala anastera, the humpbacked orbweaver, is a species of orb weaver in the family Araneidae.

[1][2] It is found in North and Central America.

The coloration can vary from tones of tan, to vivid green.

Some have a dark line along the median, as the one pictured, and many have a foliate pattern.

The legs are also quite variable, and are covered in short spines, which are most notable in males.
