Which insect is known to be associated with decaying vegetation?

Fungus gnats are particularly associated with decaying vegetation as their larvae thrive in damp, decaying organic matter, especially in the soil of potted plants. These insects are attracted to conditions where organic decomposition is taking place, as it provides the necessary nutrients for their development. The presence of decaying plant material creates an ideal environment for fungus gnats to lay their eggs, leading to an infestation that can be problematic for plant health.

In contrast, while ants may forage for various food sources, including decaying matter, they are more often associated with a variety of habitats and food sources rather than specifically tied to decaying vegetation. Fruit flies are typically linked to overripe or rotting fruits and vegetables rather than decayed plant materials in soil. Moths, on the other hand, have different associations, often linked to fabrics or stored food rather than decaying vegetation, making fungus gnats the most directly connected to this specific condition.
