Details

Lynx spiders are active hunting spiders belonging to the family Oxyopidae. They are best known for their agility, good vision and spiny legs, and are commonly found on grasses, shrubs and flowers in warm and temperate regions worldwide.

Basic Biology

Scientific scope: Family Oxyopidae – lynx spiders (e.g. genera Oxyopes, Peucetia)
Size: Small to medium; most species about 3–25 mm in body length, many common species 5–15 mm.
Longevity: Typically around 1 year, occasionally up to 1–2 years in favourable conditions.

Ecology & Hunting Behaviour

Lynx spiders make little or no use of prey-catching webs. Instead they live as active foliage hunters, running and leaping among leaves and stems. Many species frequent flowers and ambush visiting pollinators or other insects, in a manner similar to crab spiders.

They have relatively good eyesight for spiders and react quickly to movement. Some species move rapidly through vegetation, while others rely more on sit-and-wait tactics, lunging at prey that comes within reach.

Morphology

Members of Oxyopidae typically have a high carapace, a characteristic eye arrangement, and legs armed with numerous, erect spines that can form a basket-like structure around captured prey. Colouration ranges from green and yellow to brown, often with stripes or spots that provide camouflage among foliage and flowers.

Venom & Human Interactions

Lynx spiders use venom to subdue insects and other small arthropods. Bites to humans are uncommon and usually mild, causing short-lived local pain, redness or itching. They are not regarded as dangerous to healthy people and generally flee rather than bite when disturbed.

Ecological Role

By feeding on aphids, leafhoppers, caterpillars and other crop pests, lynx spiders can act as useful biological control agents in agricultural systems such as cotton fields and orchards. In some cases they may also take pollinating insects, so their net effect depends on the balance of prey types, but overall they are considered beneficial predators in many habitats.
