Fireflies dance by a stream in Bijia Hill Park in Futian District. This enchanting sight is made possible by the presence of the nationally protected Ceratopteris thalictroides, commonly known as the water fern. The lush, moist environment created by this plant plays an important role in the life cycle of fireflies. Thriving in shaded or diffused light conditions, the water fern typically inhabits marshes, rice paddies, or muddy ditches. Besides being a sanctuary for fireflies, its presence is a testament to Shenzhen’s commitment to biodiversity and environmental preservation. Shenzhen Evening News
