1. Local movements of aquatic insects within the surroundings of waterbodies aim essentially to find food, mates, resting sites, or avoid predation. Distances moved are very variable among species and may also differ depending on sex or age at the intraspecific scale. Despite a large panel of studies on odonate activities near waterbodies, little is known about their movements and behaviour in the surrounding landscape matrix. This knowledge is, however, crucial to support management schemes of pond networks and allow improvement of connectivity between them.
2. In this study, 87 individuals of the large dragonfly Anax imperator were identified with a unique code on the wings and monitored visually on five ponds during summers 2017 and 2018. Simultaneously, 54 individuals were equipped with radio transmitters and tracked for up to 15 days.
3. We built Cormack Jolly Seber models to test which factors are important for movement and survival of individuals, and calculated home ranges. Additionally, we performed a step selection analysis on the telemetry data to identify the terrestrial habitats selected by A. imperator at the interface between a rural area and a suburban area in north‐western France.
4. A reduction of the survival rate was observed on the day immediately following capture regardless of the marking method. Individuals equipped with radio transmitters had a lower estimated daily survival (0.78; 95% confidence interval = 0.70–0.85) compared to wing‐marked individuals (0.89; 95% confidence interval = 0.85–0.92). Wing loading and age were the main variables influencing dragonfly survival for both methods.
5. The probability of movement between ponds was similar for both sexes, but radio‐tracking data showed that females moved significantly further away in the landscape matrix than males, with one female detected up to 1,902 m away from the release pond. Females also had a larger home range (mean 95% kernel: 50 ha) than males (mean 95% kernel: 5 ha). Reproductive behaviour of males and flying behaviour of females were positively related to air temperature. Individuals of both sexes were present on ponds more often than in all other habitats whatever their activity. High trees were the preferred place to rest when air temperatures were low, especially for females.
6. Overall, this study highlights the importance of integrating neighbouring trees in management schemes of ponds. It also confirms that preservation of pond networks must include on several hectares of land around ponds to meet the aquatic and terrestrial needs of amphibious organisms such as odonates. Our radio‐tracking data provide a basis for further studies on the persistence of odonate meta‐populations in fragmented landscapes.

池塘网络中大型蜻蜓（Odonata：Anax imperator）的栖息地利用和活动

1. 水生昆虫在水体周围的局部运动主要是为了寻找食物，伴侣，休憩场所或避免被捕食。不同物种之间移动的距离非常不同，并且在种内尺度上也可能取决于性别或年龄。尽管对水体附近的卵酸盐活动进行了大量研究，但对其在周围景观矩阵中的运动和行为知之甚少。但是，此知识对于支持池塘网络的管理方案并改善它们之间的连接性至关重要。
2. 在这项研究中，在2017年和2018年夏季，识别出87头大型蜻蜓Anax推进器的机翼，并在其机翼上使用了唯一的代码，并在五个池塘上进行了可视化监控。同时，有54头人配备了无线电发射器并进行了长达15天的跟踪。
3. 我们建立了Cormack Jolly Seber模型，以测试哪些因素对个人的移动和生存至关重要，并计算出房屋范围。此外，我们对遥测数据进行了分步选择分析，以识别由A. imperator在法国西北部农村地区和郊区之间的界面处选择的陆地栖息地。
4. 不论标记方法如何，在捕获后的第二天观察到存活率的降低。配备无线电发射器的个体的每日估计生存率较低（0.78； 95％的置信区间= 0.70–0.85），而带有机翼标记的个体（0.89； 95％的置信区间= 0.85-0.92）。两种方法中，翼的负荷和年龄是影响蜻蜓生存的主要变量。
5. 男女之间池塘之间移动的可能性相似，但是无线电跟踪数据显示，雌性在景观矩阵中的移动距离比雄性大得多，其中一名雌性离释放池塘的距离最大为1,902 m。女性的家境（平均95％籽粒：50公顷）也比男性（平均95％籽粒：5公顷）更大。男性的生殖行为和女性的飞行行为与气温呈正相关。无论其活动如何，与所有其他栖息地相比，性别个体出现在池塘上的频率更高。当气温低时，高树是最好的休息场所，尤其是对于雌性树。
6. 总的来说，这项研究强调了在池塘管理方案中整合相邻树木的重要性。它还证实，池塘网络的保护必须包括池塘周围数公顷的土地，以满足两栖生物（如卵酸盐）的水生和陆地需求。我们的无线电跟踪数据为进一步研究零散景观中的卵酸盐亚群的持久性奠定了基础。
