abstract: The mating was studied for a cave-living Coleoptera Bathysciinae, Speonomus delarouzeei , and consists of three behavioural units : a short pre-mating phase (55 s), a short resting phase (50 s) and a longer mating phase (5 min 20 s). When the female is in a receptive condition, numerous matings occur, separated by a more or less long time ; between the copulations the male remains behind the female, both forming thus a "pair" which may last 48 hours. One female can copulate successively with several males. The males behavior which always follow the females between two matings allows to think that a female pheromone is produced and stimulates the males at a very short distance.
