11-5-2025 MONTE CORONA, VALENCIA - COMMON GARBAGE LINE WEB SPIDER (Cyclosa insulana)

The "Garbage-Line Web Spider," also known as a trashline orbweaver, is a spider belonging to the genus Cyclosa. These orb-weaver spiders are characterized by building webs that include a linear decoration of debris, often including prey remains and other materials, which likely aids in camouflage. The spider itself often rests in the center of the web, within this trashline, camouflaged by the debris. 

Genus Cyclosa of the orb weaving Areneidae family is also called the Garbage Line Spider because they have radial lines of thickened silk that contains the remains of their prey with the spider hidden in the line in the centre of the web. Perhaps the spider's lumpy shape helps it to look like the other detritus.

Here's a more detailed look at the Garbage-Line Web Spider:

Genus: Cyclosa. 

Common Name: Trashline orbweaver, Garbage-Line Spider. 

Web Structure: Cyclosa spiders build relatively small, circular orb webs. 

Web Decoration: They create a distinctive "garbage line" or stabilimentum by incorporating debris like prey remains, exuvia (shed skin), and other materials into their web. 

Camouflage: The spider itself often rests within the center of the web, within this trashline, blending in with the debris. 

Distribution: Cyclosa spiders are found worldwide.
