Syrphidae - Flower Flies, Hover Flies, Rattail Maggots

Flower, or hover, flies are a large group of flies with broad ecological diversity. Most species are terrestrial, with larvae feeding on decaying fungal or plant matter, but some are adapted as feeders of decaying organic matter in stagnant aquatic or semi-aquatic environments, and show remarkable physical adaptations to respiratory challenges. Some larvae have very long terminal repiratory siphons, giving them the moniker "rattails". Some groups also have terrestrial and even aquatic predatory forms. Adults are important pollinators of plants, and many show remarkable mimicry of bees and wasps.

The systematics of the family are in flux, with currently four subfamilies recognized: Syrphinae, Microdontinae, Eristalinae and Pipizinae, the latter only recently being elevated (Mengual et al. 2015), and the Eristalinae likely being paraphyletic (Young et al. 2016). We are fortunate for a recent field guide by Skevington et al. (2019a), which has provided an update to the flower flies of Northeastern North America. They have also proposed common names, which have been incorporated in the list below, and provided taxonomic clarification for a number of groups needing revision.

Genera are denoted in green; species denoted in bold blue have been recorded in Michigan; species denoted in black bold are likely to occur in Michigan based on their known distribution with nearby state/provincial localities from which certified records have been published. You can use the Find function in your web browser to locate families, genera, and species. Synonomous species (indented) are listed below the current valid species (denoted in bold) with its taxonomic status indicated.
