查了一下synchronous fireflies，smoky mountains和congaree np都有，说是两周左右。smoky mountains是在五月第三周到六月第三周之间，需要抽签观看。congaree不知道。你去看过吗？是很密集还是比较稀稀拉拉的？萤火虫好像只能发一个晚上的光是吧？记得令狐冲给岳灵珊抓了很多，放在袋子里；第二天都死了……

Why the synchrony?
Researchers have investigated the reasons behind this synchronized flashing behavior; however, the synchronous behavior is not yet fully understood. One theory suggests that males flash in unison to elicit a call-and-response interaction from the females. A study found that female fireflies of this species only respond when an adequate amount of flashing is presented to them. Once enough light is generated in the forest, the much dimmer females will respond during the pauses in the males' flashing pattern.
The flash pattern of Photinus carolinus is a remarkable sequence of five to eight distinct flashes, followed by an eight-second pause of darkness, before the cycle repeats. Initially, the flashing may appear random, but as more males join in, their rhythms align, creating a breathtaking display of pulsating light throughout the forest.
