The vertical prifile of the microclimate and flying adult aquatic insects directly above a mountainous stream in Kyushu, Japan

This dataset contains a comprehensive set of ecological and meteorological data collected to investigate a vertical stratification of the microclimatic conditions and the distribution of flying adult aquatic insects above a mountainous stream. The study was conducted in a headwater stream located in the Kyushu region of Japan during the summer of 2024. The insect data and the microclimate data were collected simultaneously at multiple heights of 1m, 3m, 5m, 7m, 10m, 13m, 15m, 17m, 20m, 22m, 25m, 27m, 29m, 32m, 34m, 36m, 39m, 41m, 44m, 46m, 48m, 50m, 52m, 55m, 57m and 3m, 7m, 17m, 27m, 36m, 48m, 57m to create a detailed vertical profile, respectively. The dataset includes mean and standard diviation of air temperature and relative humidity, as well as the abundance and taxonomic composition of adult aquatic insects (e.g., Ephemeroptera, Plecoptera, Trichoptera) captured at each height.
