Garden orb‑weaving spiders are a loose group of species within the family Araneidae, including common genera such as Eriophora and Neoscona. They are best known for building classic circular orb webs in gardens, shrubs and forest edges, where they are important nocturnal predators of flying insects.
Basic Biology
Scientific scope: Family Araneidae – garden orb‑weaving spiders (e.g. Eriophora spp.)
Size: Most females 10–25 mm body length; males smaller.
Longevity: Typically around 1 year, some species 1–2 years.
Ecology & Behaviour
Many species construct their webs at dusk, sit at the hub or on a signal line at night, and may consume or abandon the web by morning. Prey includes moths, flies, mosquitoes and small beetles, making them valuable allies in natural pest control around homes and gardens.
Venom & Human Interactions
Like most spiders, garden orb‑weavers have venom to subdue prey, but bites to humans areusually mild, causing local pain and redness comparable to a bee sting. They are not regarded as medically significant in healthy individuals and rarely bite unless handled or pressed.
Role in the Garden
By removing large numbers of nocturnal flying insects, garden orb‑weavers act as “living pesticides”. Maintaining plant diversity, lighting that is not overly harsh, and reduced insecticide use all help sustain their populations and overall garden biodiversity.
