Insect phenological lability is key for determining which species will adapt under environmental change. However, little is known about when adult insect activity terminates and overall activity duration. We used community-science and museum specimen data to investigate the effects of climate and urbanisation on timing of adult insect activity for 101 species varying in life history traits. We found detritivores and species with aquatic larval stages extend activity periods most rapidly in response to increasing regional temperature. Conversely, species with subterranean larval stages have relatively constant durations regardless of regional temperature. Species extended their period of adult activity similarly in warmer conditions regardless of voltinism classification. Longer adult durations may represent a general response to warming, but voltinism data in subtropical environments are likely underreported. This effort provides a framework to address the drivers of adult insect phenology at continental scales and a basis for predicting species response to environmental change.

成虫活动的气候驱动因素受生活史特征的影响

昆虫物候不稳定性是确定哪些物种将适应环境变化的关键。然而，关于成虫活动何时终止和总活动持续时间知之甚少。我们使用社区科学和博物馆标本数据来研究气候和城市化对 101 个生活史特征不同的物种的成虫活动时间的影响。我们发现碎屑动物和具有水生幼虫阶段的物种会随着区域温度的升高而最迅速地延长活动期。相反，无论区域温度如何，具有地下幼虫阶段的物种都具有相对恒定的持续时间。无论伏汀病分类如何，物种在温暖的条件下类似地延长了它们的成年活动期。更长的成人持续时间可能代表对变暖的普遍反应，但亚热带环境中的伏打数据可能被低估了。这项工作提供了一个框架来解决大陆尺度上成虫物候的驱动因素，并为预测物种对环境变化的反应奠定了基础。
