Do mayfly nymphs identify good or poor water quality?

Yes, mayfly nymphs can serve as indicators of water quality. They are sensitive to pollution and changes in their environment, so their presence typically signifies good water quality, while their absence or a decline in their population may indicate poor water conditions. Monitoring mayfly populations can thus be useful for assessing ecosystem health.

Mayflies are sensitive to changes in water quality, so their presence or absence can indicate the health of a water body. High levels of pollution can harm mayfly populations, leading to declines in their numbers. By studying mayflies in a water system, scientists can assess pollution levels and overall ecosystem health.
