我们调查的假设，无耳蛾保卫自己从蝙蝠在东南部的安大略网站通过他们的飞行行为。在这项研究中，我们假设蛾从静止的栖木开始飞行（飞行倾向）所需的时间将反映其整个夜间的飞行。我们预测，无耳蛾将表现出相对于有耳蛾减少飞行趋势，因为在这个网站上的蛾主要是在飞行时被蝙蝠捕食的风险。当分组时，无耳类群显示出显着更大的平均间隔飞行离开比有耳类群。大多数物种的无耳家庭Saturniidae，Sphingidae和Lasiocampidae更有可能保持静止，并采取更长的时间开始飞行比成员的有耳家庭夜蛾科，Notodontidae，Geometridae，Arctiidae和Drepanidae。我们的结论是，对于大多数无耳蛾的假设，减少飞行防御的支持，但也有例外，我们的研究结果表明，E。
We investigated the hypothesis that earless moths defend themselves from bats in a southeastern Ontario site by means of their flight behaviour. In this study we assume that the time taken by a moth to initiate flight from a stationary perch (flight tendency) will reflect its overall flightedness throughout the night. We predicted that earless moths would exhibit a reduced flight tendency relative to eared moths because moths at this site are primarily at risk of predation from bats while flying. When grouped, earless taxa displayed a significantly greater mean interval to flight departure than eared taxa. Most species of the earless families Saturniidae, Sphingidae, and Lasiocampidae were more likely to remain stationary and took longer to initiate flight than members of the eared families Noctuidae, Notodontidae, Geometridae, Arctiidae, and Drepanidae. We conclude that for most earless moths the hypothesis of reduced flight defence is supported, but there are exceptions to our results that suggest the e...
