Abstract

The article focuses on the unique defensive behavior of certain spider species that create large doppelgängers to deter predators. Researchers observed two orb-weaving spiders, Cyclosa longicauda in Peru and an unidentified Cyclosa species in the Philippines, constructing these decoys from silk, animal remains, and plant material. The spiders build these lookalikes quickly, often within 90 minutes, during the night to avoid being seen by predators. Additionally, the design of the decoys may mimic bird droppings, further reducing the likelihood of being attacked by birds. [Extracted from the article]
