“…There are also data from the Neotropical Region that indicate that populations of adult Sciomyzidae are inversely correlated with rainfall. Knutson & Carvalho (1989) found that 172 specimens of 2 species of Thecomyia (probably aquatic predators) collected at 1 site near Belém, Brazil on 49 dates during 1977 and 1978 were taken just before and after the rainy season. Mello & Bredt (1978) made monthly collections of 5 species of Sepedonea Steyskal and 1 species of Sepedomerus Steyskal (aquatic predators) during 1975 and 1976 near Brasilia, Brazil and found that populations peaks occurred as the period of heaviest rainfall declined, with adults of some species found during every month of 1 of the years.…”

Predation by larvae of Sepedon ruficeps (Diptera: Sciomyzidae) and population dynamics of the adult flies and their freshwater prey. -The biology, phenology, and population dynamics of the adults of Sepedon ruficeps, the most widely distributed species of Sciomyzidae in Africa, were studied in Benin in permanent and temporary freshwater habitats. The feeding behavior of the larvae, expressed as the number of snails consumed, varies as a function of the species of prey utilized (Bulinus forskalii or Biomphalaria pfeifferi), as a function of the sizes of the predator/prey, and as a function of the stages of development of the larvae. In relation to the snail-prey, the second-and third instar-larvae show a food choice varying according to the specific ethology of the prey attacked. In all cases, the third-instar larvae always consume the largest number of snails and indifferently attack all of the species of snails utilized in laboratory rearings. The larvae consume, equally well, B. forskalii that are healthy or parasitized by the larvae of trematodes. Curiously, in laboratory rearings, in the absence of snails, the larvae of S. ruficeps are equally capable of attacking and developing at the expense of Aulophorus furcatus, a small, freshwater, oligochaete annelid (Naididae).

“…Adult sciomyzids are not attracted by flowers, and there is little information about which kinds of vegetation they prefer (Knutson and Vala 2011 by Malaise traps (Marinoni et al 2004;Knutson and Carvalho 1989), making net sweeping the best collecting method for these flies. Most specimens are collected while sweeping the vegetation surrounding the water bodies inhabited by mollusks.…”

An inventory of the species of Sciomyzidae that occur in the Coastal Plains of southern Brazil was conducted. Sampling resulted in 304 specimens, 278 of which were collected with nets and 26 with Malaise traps. A total of 11 species distributed in eight genera were collected. New distribution records for Protodictya iguassu Steyskal, 1950 and Thecomyia lateralis (Walker, 1858) are recorded from Rio Grande do Sul.

Treated herein are the 113 described species and two described subspecies in 25 genera of the family Sciomyzidae (snail-killing or marsh flies) known from the Americas south of the United States. Included are details on type specimens, references to generic transfers and synonymies, taxonomy, biology, gastropod hosts/prey, immature stages, chromosomes, biological and phenological groups, general distribution, and molecular data. Annotated keys are presented to adults of genera known from the Nearctic-Neotropical interface area and the Neotropics as well as the first key to all sciomyzid genera known from the Nearctic Region. Also presented is the first key to third-instar sciomyzid larvae in the Neotropical Region. Sepedonea isthmi (Steyskal) is placed as a junior synonym of S. annulata Macquart (new status), and Tetanocera plumifera Wulp is placed as a junior synonym of T. plumosa Loew (new status).
