Description:

The large yellow abdomen with either black or orange markings is diagnostic. Male spiders are not often seen because they do not typically make webs.

Where to find:

"Marbled Orbweavers build extensive orb webs but when startled they leave their larger webs to hid in small retreat webs usually well out of sight" (Richard Orr).

There are 309 records in the project database.
