Studies suggest that light pollution around lakes prevents zooplankton, such as "Daphnia", from eating surface algae, causing algal blooms that can kill off the lakes' plants and lower water quality. Light pollution may also affect ecosystems in other ways. For example, lepidopterists and entomologists have documented that nighttime light may interfere with the ability of moths and other nocturnal insects to navigate. Night-blooming flowers that depend on moths for pollination may be affected by night lighting, as there is no replacement pollinator that would not be affected by the artificial light. This can lead to species decline of plants that are unable to reproduce, and change an area's longterm ecology. Among nocturnal insects, fireflies (Coleoptera: Lampyridae, Phengodidae and Elateridae) are especially interesting study objects for light pollution, once they depend on their own light to reproduce and, consequently, are very sensitive to environmental levels of light. Fireflies are well known and interesting to the general public (unlike many other insects) and are easily spotted by non-experts, and, due to their sensibility and rapid response to environmental changes good bioindicators for artificial night lighting. Massive insect declines have been suggested as being at least partially mediated by artificial lights at night.
