Abstract This study examined the flight activity of adult caddisflies (order Trichoptera) in a pine-oak forest in México. Specimens were collected near the locality of Puente de los Trabajos, Sierra de Juárez, Oaxaca State using blacklight traps during four nights between 28 October and 13 November 2015. A total of 1117 specimens were collected, belonging to 10 families, 18 genera, and 28 species. Limnephilus tulatus Denning, 1962, Polycentropus casicus Denning and Sykora, 1966 and the genus Mayatrichia Mosely, 1937 are recorded for the first time from Oaxaca State. Activity and species diversity peaked between 18:00 and 19:30 h. More than 90% of all species observed had been recorded by 00:30 h, and 100% by 05:30 h. Abundance and species richness were significantly correlated with temperature and relative humidity. We found that the seasonal activity of Ochrotrichia yavesia Bueno-Soria and Holzenthal, 2004, increases in late October. Environmental variables as precipitation, wind speed and direction should also be considered, and additional sampling in different seasons of the year in other localities with different environmental conditions is also recommended.

墨西哥瓦哈卡温带森林中石蛾（昆虫纲：毛翅目）夜间飞行的初步评估

摘要 本研究调查了墨西哥松橡树林中成年石蛾（毛翅目）的飞行活动。在 2015 年 10 月 28 日至 11 月 13 日期间的四个晚上，使用黑光陷阱在瓦哈卡州华雷斯山脉 Puente de los Trabajos 附近采集了标本。共采集了 1117 个标本，分别属于 10 科、18 属和 28物种。Limnephilus tulatus Denning, 1962, Polycentropus casicus Denning and Sykora, 1966 和 Mayatricia Mosely 属, 1937 首次从瓦哈卡州记录下来。活动和物种多样性在 18:00 和 19:30 之间达到峰值。超过 90% 的观察到的物种在 00:30 时被记录，到 05:30 时已记录到 100%。丰度和物种丰富度与温度和相对湿度显着相关。我们发现 Ochrotrichia yavesia Bueno-Soria 和 Holzenthal，2004 年的季节性活动在 10 月下旬增加。还应考虑降水、风速和风向等环境变量，并建议在其他环境条件不同的地区在一年中的不同季节进行额外采样。
