Courtship display of Habronattus captiosus involves several behavioral elements common to other members of the Habronattus coecatus species group. The one unique element is vibration of the patellae when raised over the opisthosoma. Male-male interactions included an agonistic display and grappling. Fourteen male-female interactions were observed, which exhibited various combinations of display elements. There was one successful mating and one case of cannibalism by a male.
