Argiope bruennichi (Scopoli, 1772) Spider's Web Structure and Morphology of the Spinneret

Abstract

Spiders are one of the groups that best adapted to terrestrial life among in invertebrates and are represented by approximately 48,000 species in the world. Although all spiders do not weave webs, the webs of spiders are literally a work of art. The main reason for spider web weaving is hunting. Some spider species live in the nature dependent on the own web, while others continue to live without being dependent on the own web. Although basic taxonomic features generally remain unchanged, some spider-silk weaving apparatus may undergo adaptive variations. In this study, the web structure of the weaving web spider, Argiope bruennichi (Scopoli, 1772) and the structural organization of the web weaving apparatus was observed by using scanning electron microscopy (SEM). The web structure of A. bruennichi, spinnerets especially posterior spinneret and arrangement of its spigots are shown and discussed in the light of the literature.
