Dolichognatha pentagona
Dolichognatha pentagona is a species of long-jawed orb-weaver spider in the family Tetragnathidae, first described by Hentz in 1850. It occurs from the United States through Central America to Venezuela. The genus Dolichognatha is widespread in tropical and subtropical regions. As a tetragnathid, it likely constructs orb webs for prey capture, though specific behavioral details for this species remain poorly documented.
Tetragnatha guatemalensis
Guatemalan long-jawed spider
Tetragnatha guatemalensis is a long-jawed orb weaver spider notable for its exceptional social behavior among typically solitary arachnids. Under favorable conditions, particularly during mass emergence of midges, this species constructs extensive communal webs that can span acres. The species demonstrates remarkable tolerance of conspecifics, with thousands of individuals cooperating to build shared silk structures. This social web-building represents the extreme end of a gradient of tolerance seen across the genus Tetragnatha.
