Sunlight and shadow position at larval habitats. A The breeding sites (blue circles) of Wolgot-myeon and Naega-myeon are surrounded by two hilly mountains, creating a valley. The black scale bar indicates 1Â km. Lands depict a range of elevation in meters above mean sea level using The National Geologic Map Database (https://ngmdb.usgs.gov/ngmdb/ngmdb_home.html). The ground area of the valley (blue dot-lined zone), including breeding sites (within a 50Â m contour line), was calculated by circumference line using Google Earth tools. B Sun (red circle) posed at that time, and thus, dark shades generated by altitude area at mountain ridge line at each time are depicted using Shadow Calculator (http://shadowcalculator.eu). The white scale bar indicates 0.1Â km. C The shadow was confirmed at each spot by taking a picture at 6 PM
