Landscapes for scenarios of different distributions of sugar sources and outdoor resting sites. The whole square represents the village, the grey dots in the center represent houses, the green dots represent natural sugar sources, the light blue dots represent outdoor resting sites, and the dark blue dots represent breeding sites. Subfigures (a) to (f) represents sugar source numbers of 0, 5, 25, 50, 75 and 100, respectively, with 50 randomly located outdoor resting sites. Subfigures (g) to (l) and (c) represent outdoor resting site numbers of 0, 5, 10, 20, 30, 40, respectively, with 25 randomly located sugar sources. Subfigures (m) and (n) represent random distributions and adjacent distributions of sugar sources with outdoor resting sites. Dots representing sugar sources are hidden behind the outdoor resting sites when they have the same location. Subfigures (c) and (o) represent random distribution and adjacent distribution of sugar sources with houses. Dots representing sugar sources are hidden behind houses when they have the same location.
