アメリカ内務省さんのインスタグラム写真 - (アメリカ内務省Instagram)「Deep in the enchanting woods of Great Smoky Mountains National Park, fireflies perform their mesmerizing light show over a two-week period between mid-May to mid-June. Synchronous #fireflies are among the 19 species found in the park. They sync up their flashing patterns, timing everything like a luminous dance number. They require an extremely dark environment to stay coordinated, and any light that enters the area throws off their whole performance. Their presence beckons to photographers and viewers alike, to explore the #Appalachian forests of #Tennessee and #NorthCarolina after dark --with eyes peeled for flashing. This image is a combination of close to 100 photos with long exposure. What a magical place this world is, especially with these dazzling beetles.
