对致倦库蚊（Culex pipiens quinquefasciatus Say）成群的视频记录的分析表明，雄性和处女雌性的总体群集模式是相似的，尽管飞行的短期特征（如速度和转向角度）不同。这表明它们对蜂群“标记”的视觉提示有相同的反应。一个个体的群集模式由椭圆形的环组成，在短期内，它定义了一个比整个群体更小的区域。这些椭圆的焦点相对于标记逐渐漂移;个体似乎在群内没有首选位置，而是随机漂移。雄性蚊子通过拍打翅膀的声音来识别和定位雌性蚊子。在雌性C. p. quinquefasciatus（500-600 Hz）的频率会导致蜂群内的雄性显著减慢速度。它们的转向行为保持不变，所以椭圆的大小减小了。蜂群作为一个整体坍缩成一个更小的体积，以标记为中心。显然，雄性对声音的反应至少包括两个部分：首先，它们改变飞行速度，然后，一旦它们找到了声音的来源，它们就会改变转弯的行为。
Analysis of video recordings of Culex pipiens quinquefasciatus Say swarms showed that the overall swarming patterns of males and virgin females are similar, even though the short-term characteristics of the flight, such as speed and turning angle, differ. This suggests they have the same response to the visual cue of the swarm ''marker''. The swarming pattern of an individual consists of elliptical loops which, in the short-term, define an area smaller than the swarm as a whole. The foci of these ellipses drift gradually with respect to the marker; individuals do not seem to have preferred positions within the swarm, but drift at random. Male mosquitoes identify and locate females by the sound of their wing-beats. Diffuse sound at the wing-beat frequency of females C. p. quinquefasciatus (500-600 Hz) caused males within the swarm to slow down significantly. Their turning behaviour remained unchanged, so the ellipses decreased in size. The swarm as a whole collapsed into a smaller volume, centered over the marker. Apparently, the response of males to sound consists of at least two parts: initially they alter their flight speed, and then alter their turning behaviour once they have located the source of the sound.
