SCIOMYZIDAE Fallén, 1820 (Marsh Flies)

Marsh flies occur in lake margins, ponds, swamps, marshes, vernal pools and wet pastures or mesic habitats where larvae are oligate parasites or predators of freshwater snails (Fisher and Orth, 1983). William Murphy (Fishers, Indiana) kindly provided additional information on updates to nomenclature and species distributions.

    Added information on distributions and nomenclature from William Murphy (pers.comm. Dec. 2012):
    • Antichaeta is now spelled Anticheta;
    • Some or all Dictya stricta records from Michigan, especially any north of Saginaw, are D. hudsonica;
    • Current name used for Pherbellia maculata Cresson in North America is P. schoenherri maculata (Cresson) to avoid confusion with the Palearctic P. s. schoenherri;
    • Current name used for Pherbellia nana (Fallén) in North America is P. nana nana (Fallén) to avoid confusion with the Palearctic P. nana reticulata;
    • Current name for Pherbellia parallela (Walker) is Ditaeniella parallela (Walker);
    • Renocera cyathiformis Melander is now R. striata (Meigen) - Knutson LV, Mathis WN, Chapman EG. (in prep.). Taxonomy, cladistic analysis, and biology of clam-killing flies of the genus Renocera Hendel (Diptera: Sciomyzidae);
    • Sepedon tenuicornis probably does not occur in Michigan, farthest northern record is Toledo, Ohio. This will remain a "likely species" due to the proximity of the Toledo record to Michigan. Note that Orth 1986 describes S. gracilicornis ranging as far north as "New York near the southern shores of Lake Ontario." The very similar S. gracilicornis is far more likely in Michigan and has been confused with S. tenuicornis in the past;
    • Sepedon americana Steyskal formerly was called S. spinipes americana, elevated to full species by Elberg et al. (2009).;
    • Sepedon fuscipennis is no longer separated with the forms fuscipennis and nobilis. DNA analyses show no significant difference, and because the only external difference is that the parafrontal spots grow more distinct as one moves south (clinal?).
    November 21, 2012
    • Beginning to keep track of changes to the web site pages
    • Removed individual pages for families into one long list, families accessed from left menu via anchor redirects within page; larger groups retained as separate pages
