Nursery Web Spider
Pisaura mirabilis
- Order & Family
- Order Araneae, Family Pisauridae
- Size
- Body length typically 10-15 mm (females are larger than males).
Natural Habitat
Found in tall grass, low shrubs, and meadows, often near edges of woodlands or gardens.
Diet & Feeding
Carnivorous; hunts various small insects such as flies, beetles, and smaller spiders by active stalking rather than using a web.
Behavior Patterns
Active hunters during the day. Females are known for carrying their large egg sacs with their chelicerae and building a protective silk 'nursery web' for the spiderlings once they are ready to hatch.
Risks & Benefits
Benefits the ecosystem by controlling pest insect populations. While they are venomous to their prey, they are not considered dangerous to humans; bites are rare and only occur if the spider is roughly handled, usually resulting in minor localized irritation.
