Catching Flies With Honey(dew): Adult Marsh Flies (Diptera: Sciomyzidae) Utilize Sugary Secretions for High-Carbohydrate Diets.

Marsh flies are a diverse family that provide valuable ecosystem services, including the biological control of mollusks that are agricultural pests and vectors of animal and human parasitic diseases. In addition, some species may serve as important ecological bioindicators. Despite the extensive research on this family, most have centered on larval diet and behavior, as this is the life stage primarily used for biological control; virtually nothing is known about the natural dietary components of adult marsh flies.
