part_of assembly in station-keeping swarm Among some families of Culicimorpha, including the Culicidae, the eyes of males are not especially developed but certain auditory organs are, and the detection of females depends upon hearing. In these flies, the verticillate antennae and highly developed Johnston's organs mediate a sensitivity to the flight tone of conspecific females. Station-keeping swarms are formed by the members of certain families of Diptera, Ephemeroptera and Trichoptera, and to a lesser extend by representatives of the Hymenoptera and a few other insect orders. The assembly station is attended by both sexes, but usually the males fly there for long periods whareas the females remain only long enough to mate(Sivinski amd Petersson, 1997). IDOMAL:0002074 IDOMAL:0002074 The males of a number of diptera taxa aggregate in aerials swarms over conspicuous objects or 'swarm markers'. Conspecific females individually fly to these swarms, but little is known of the responses that take them there. At the assembly stations where male and female insects meet, the females usually are recognized by vision, and among insects that form aerial swarms the eyes of the male are specially developed. idomal_namespace formation of assembly hearing response during mating response to visual stimulus during mating swarming assembly in station-keeping swarm Among some families of Culicimorpha, including the Culicidae, the eyes of males are not especially developed but certain auditory organs are, and the detection of females depends upon hearing.
