description Trash-line Orbweaver (Cyclosa conica) Overview
The trash-line orbweaver (Cyclosa conica) is a small spider found across the Holarctic region, encompassing parts of North America, Europe, and Asia.

This structure consists of discarded prey remains, egg sacs, and plant material arranged in a line through the center of the orb web. The spider rests within this line, using the collected debris as visual camouflage against predators.
