Silver-sided sector spider

Silver-sided sector spider

Zygiella x-notata

A species of Zygiella, Also known as Missing-sector orbweb spider

The silver-sided sector spider is known for its distinctive web, with a spiral shape and a single sector missing from it. The empty sector has only a single thread crossing it, which connects to the spider and alerts it to the presence of captured prey through the vibration. The young spiders rebuild their web every day until adulthood.
