Although chorusing behaviour has been reported previously in six species of corixid water bugs, including one European species of Micronecta, no analysis of chorusing has been published for Micronecta. Studies of a large pond in SE Australia show that chorusing occurred in the most common species ofMicronecta in the study area, M. concordia. Pulse-trains synchronized with those of other individuals nearby were the predominant acoustic output of M. concordia males throughout the stridulating season, from mid-winter to mid-summer. At the start of the season, chorusing began with an exponential increase in the percentage of synchronized signals over a period of six days.
