Its debris string

The three-pronged tail is a characteristic of Cyclosa species but is variable in appearance between species and even within the same species. The same variability is seen in the spiders' surface markings.

Cyclosa species typically build a web with a central component of heavy zigzag silk but there may also (or alternatively) be a string of insect debris stretched across their web.

Spider(s) with a very similar appearance: Cyclosa species.
