The present paper provides a review of literature data and of the author's own data on the behaviour of house crickets (Acheta domesticus L.) during encounters with conspecifics. Three main categories of intraspecific behaviour are: sexual behaviour, aggressive behaviour and parasocial behaviour. House crickets use four main modes of sensory perception and signalling: acoustic, olfactory, visual and tactile. The three basic types of song are: (1) calling song, (2) courtship song, and (3) aggressive song. Sexual behaviour of house crickets involves courtship, mating, and guarding of the female by the male. Aggressive behaviour is observed mostly during territorial fights between males. However, food deprived females may fight, too, when competing for food. In laboratory mass cultures, aggressiveness of crickets is usually very low, and territorial behaviour is absent. However, crickets may show territorial behaviour even in the laboratory if they are kept in sufficiently large cages. Males and females of A. domesticus produce sex-specific, species-specific and aggregation pheromones. Aggregations of crickets are non-coordinated and temporary. Growth and development of house crickets may be significantly accelerated as a consequence of intense contacts with conspecifics ("the group effect"). Mechanisms underlying the group effect are yet not fully known. However, it is already known that they are based on responses to stimuli transmitted by the antennae and cerci, and that they involve responses to pheromones.
