Other information：They are commonly found in lowland abandoned farmlands and bamboo forests, sometimes appearing in thousands simultaneously. The male fireflies flash at intervals of about 2.5 seconds, with each flash lasting approximately 0.1 seconds and consisting of two closely spaced pulses.In my experiments, I found that their larvae feed exclusively on small cone snails.

其他资料：多在低地废弃农田、竹林中出现，有时数以千计同时出现。雄萤闪光间隔约2.5秒，每个闪光维持约0.1秒，由两个紧接的脉冲组成。在本人试验中，发现其幼虫只食用小型的锥形螺。
