Habitat Preferences of Marsh fly Through Different Life Stages
For marsh fly, larvae are typically found in wet environments with decomposing vegetation, such as marshes or the edges of ponds, where they consume snails. In search of these larvae, look among decaying leaves and submerged logs. Pupae commonly inhabit drier, sheltered areas nearby, often in loose soil or under layers of dead leaves. To find them, gently dig around the edges of larvae habitats or examine the underside of fallen foliage. Adult marsh fly are often seen around water bodies, as well as in meadows or near woods, where they feed on flower nectar. Seeking adults involves observing flowers or sunny, open areas where they may be flying or resting.
