Many hoverfly species show specific or non specific morphological resemblance to wasps (Vespula sp.) and it has been suggested that they also show similar flight behaviour. In this study we therefore compared the flight behaviour of wasps with that of four mimetic hoverflies, Sericomyia silentis, Myathropa florea, Helophilus sp. and Syrphus sp., by filming insects while they were foraging on an artificial array of flowers. Films were analysed to determine the routes taken, time spent hovering and flight speed. Of the four flies, only the non specific mimic, Syrphus, showed similar flight behaviour to the wasps; it flew more slowly, and with more roundabout routes than the other flies, hesitating before landing. These results suggest that in hoverflies there is little reason to expect strict correlation between morphological and behavioural mimicry; insects may acquire the similarities to their model more-or-less independently.
许多食蚜蝇物种在形态上与黄蜂（黄蜂属）表现出特定或非特定的相似性，并且有人认为它们也表现出类似的飞行行为。因此，在本研究中，我们通过拍摄昆虫在人工花丛中觅食时的情况，比较了黄蜂与四种拟态食蚜蝇（静食蚜蝇、华丽食蚜蝇、黄腹食蚜蝇属和食蚜蝇属）的飞行行为。对影片进行分析，以确定它们所采取的路线、悬停时间和飞行速度。在这四种食蚜蝇中，只有非特定拟态的食蚜蝇属表现出与黄蜂相似的飞行行为；它飞行速度较慢，路线比其他食蚜蝇更迂回，着陆前会犹豫。这些结果表明，在食蚜蝇中，没有理由期望形态拟态和行为拟态之间存在严格的相关性；昆虫可能或多或少独立地获得与它们的模型的相似性。
