Additional information
in colonies in burrows of up to 10 cm depth (1 cm diameter), covered by small shield- or funnel-like web. Female carries lens-shaped cocoon (8-10 mm diameter, approximately 65-100 eggs) to sunny places during the day. Hatching juveniles stay in the female's burrow and feed on her after her death.
This species can bite humans. A bite into a finger caused pain, spreading to the axilla, with fever-like symptoms and an increased heart rate. After one hour the patient had partially recovered and after 2 hours the symptoms had alleviated, but a strong headache lasted for one day and the finger remained sensitive for several days.
