What are nymphs prey?

Nymphs, which are juvenile forms of insects such as dragonflies, mayflies, and stoneflies, primarily feed on small aquatic organisms. Their prey typically includes algae, detritus, and smaller invertebrates like other insects, larvae, and crustaceans. The specific diet can vary depending on the species and habitat, but they play an essential role in aquatic ecosystems as both predators and prey.
