Oecobiidae

The combination of evenly radiating leg placement around the prosoma (rather than forward/backward orientation), the distinctive scurrying wheel-like movement pattern, and the anal gland with tuft of long hairs distinguishes Oecobiidae from other spider families. The flat, star-shaped webs on walls or rocks are also characteristic. Cribellate silk is present in Oecobius but absent in Uroctea.

Rocky substrates, walls, and gravel surfaces; many species are synanthropic and occur on building walls, in entrances, on window sills, and near ceilings of human dwellings. Desert-dwelling species tend to be larger. Shelter from direct sunlight and rainfall appears important for some species.

Cosmopolitan distribution; Oecobius navus occurs worldwide. Documented from Europe, Asia (Iran, Afghanistan, Turkmenistan, India, Kazakhstan, Turkey, China), Africa, Australia, and the Americas. Specific regional records include Ukraine, Greece, Crete, and the Thar Desert in India.

Activity patterns vary by species and locality. In Oecobius rhodiensis, adults observed June–July with highest abundance May–October on building exteriors; individuals found inside buildings in April and November. Juveniles generally more abundant than adults in populations studied.

Ants form a major prey component; Oecobius navus preys primarily on the red meat ant Iridomyrmex chasei. Spiders hide near or below their webs to capture prey.

Development includes egg, nymphal stages, and adult. Photoperiod affects nymphal development in at least one species (Oecobius annulipes). Adults of Oecobius rhodiensis observed June–July. Juveniles generally more abundant than adults in field populations.

Constructs small, temporary, flat star-shaped webs on or under rocks, walls, or gravel. Hides near or below webs to ambush prey. Exhibits distinctive scurrying, wheel-like locomotion due to leg positioning. Some species build webs close to ceilings in human dwellings. Courtship and copulation behaviors described for Oecobius concinnus; web construction and prey capture behavior studied in Oecobius annulipes.

Predator, particularly of ants; may contribute to ant population regulation in urban and natural environments.

Synanthropic species frequently found in human dwellings, where they construct small webs on walls and near ceilings. Generally considered harmless. Common names such as 'anteater' or 'miervreter' (Afrikaans) reflect ant-feeding habits. Some species may be vulnerable to desiccation and thermal stress, explaining preference for sheltered walls.
