[1] These spiders probably are more important as members of the beneficial complex of predators in agroecosystems than is generally known.

[2] One species, Atypena formosana, lives in colonies in wetland habitats, where it builds nets just above the water line in rice fields to hunt planthopper nymphs.

Many males have bizarre projections on their carapaces, including lobes, turrets, grooves, pits and modified hairs.

In a few species the females have been observed to grip the males by the pits or grooves during copulation, using their chelicerae.

They later ingested secretions produced by the male prosomic glands after depositing saliva-like fluid on them.
