Natural Habitat

Tall grass, woodlands, gardens, and low-growing vegetation throughout Europe and parts of Asia.

Diet & Feeding

Carnivorous predator feeding on a variety of small insects including flies, beetles, and midges.

Behavior Patterns

Diurnal hunters that do not spin a web to catch prey. Famous for mating rituals where the male offers the female a silk-wrapped gift (an insect). The female carries the large egg sac in her chelicerae until it is ready to hatch, at which point she builds a silk 'nursery tent' for the spiderlings.

Risks & Benefits

Generally harmless to humans; they are reluctant to bite and their venom is not medically significant. They benefit the ecosystem by controlling garden and agricultural pest populations.
