In their natural environment, these flies are parasitic on host plants, but are not often harmful to plant populations. They may reduce seed dispersal by spoiling fruit, but they don't necessarily prevent seed germination. They are prey for a wide variety of insect predators and parasites. They are much more significant in agricultural ecosystems, where they can be a major pest of fruit crops (see below).
