    Life History

    It makes a flat sheet-like silk web, typically with a tubular retreat at one corner. Male spiders are usually seen more often than females, as they wander widely in search of a mate. After a male has found a female's web he will stay with her for a number of weeks, mating with her repeatedly during this time. He then dies and the female eats him; the nutrients within the male contribute to the development of his young.
