 They are stout, squat-shaped and rather furry, with females often uniformly mottled sandy brown, while males are often black, sometimes with a pattern and with light, annulated legs.Spiders in this genus mainly catch and feed on ants (myrmecophagy).A Southeast Asian "Aelurillus" species has been observed to jump around 30-40 times its body length straight onto the back of a large gnaphosid spider and kill it.
