Leucauge
Orchard Spiders, Orchard Orbweavers, Long-jawed Orb Weavers
Leucauge is a genus of long-jawed orb-weaving spiders in the family Tetragnathidae, comprising over 170 species with pantropical distribution. The genus was established by Adam White in 1841 based on a specimen collected by Charles Darwin. Leucauge spiders are characterized by their distinctive silver, black, yellow, and green coloration, horizontal or slanted orb webs, and two rows of long, slender curved hairs on the femurs of the fourth leg. The genus underwent significant taxonomic revision in 2010 to resolve historical confusion surrounding the type species.
Leucauge venusta
Orchard Orbweaver, Orchard Spider
Leucauge venusta, commonly known as the orchard orbweaver, is a small, colorful spider in the family Tetragnathidae. It is one of the most common and visually distinctive spiders in eastern North America, recognized by its silvery-white body, green legs, and variable red or orange abdominal markings. The species builds horizontal orb webs in woodland habitats and is active primarily in late spring and early summer. Despite its common name, it is not particularly associated with orchards, preferring forest edges and shrubby vegetation.
Tetragnatha
Stretch Spiders, Long-jawed Orb Weavers
Tetragnatha is a large genus of long-jawed orb-weaving spiders with hundreds of species distributed worldwide, though most occur in tropical and subtropical regions. These spiders are characterized by their elongated bodies, extremely long legs, and notably elongated chelicerae (jaws) with well-developed teeth. They construct horizontal orb webs, often near water, and many species can run across water surfaces. The genus exhibits remarkable variation in dispersal ability, with some species being excellent dispersers capable of colonizing islands, while others appear to have secondarily lost this capacity. Hawaiian Tetragnatha species have undergone adaptive radiation, with some lineages evolving cursorial (running) behavior and abandoning web-building entirely.

Nitens long-jawed spider
Tetragnatha nitens is a long-jawed orb weaver spider with a cosmotropical distribution spanning tropical and subtropical Asia, where it is native, and numerous introduced regions including the Americas, Macaronesia, Mediterranean Europe, Africa, Madagascar, Pacific islands, and New Zealand. The species constructs horizontal orb webs in vegetation and has demonstrated ecological adaptability across diverse biomes including Fynbos, Grassland, Savanna, and Thicket. Listed as Least Concern due to its wide geographic range and presence in multiple protected areas.
