Ecology & Habitat
Habitat
Primarily found in temperate forest floors, grasslands, woodland edges, and low-vegetation areas across Northern and Central Europe. Prefers moist, dark environments with leaf litter, decaying wood, and ground-level microhabitats.
Ecological Role
Plays a crucial role in controlling insect populations, serving as an intermediate predator in terrestrial ecosystems. Helps maintain ecological balance by regulating populations of small invertebrates and acting as prey for larger predators.
Morphology
SKIN COATThick, dense exoskeleton with protective brown-gray coloration. Covered in short, stiff hairs that aid in sensory perception and environmental interaction.
LIMBS WINGSEight powerful legs with dense setae, enabling quick ground navigation and precise hunting movements. Strong chelicerae for capturing and consuming prey.
HEAD SENSORYLarge anterior eyes arranged in three rows, providing excellent peripheral vision and depth perception. Highly developed sensory capabilities for detecting prey movement and vibrations.
BODY STRUCTUREMedium-sized spider, typically 10-15 mm in body length. Robust build with strong, muscular legs adapted for rapid ground movement. Dark brown to grayish-brown coloration providing excellent camouflage.
