Abstract:Food habits of two species of dolichopodid fly larvae, from two Gulf Coast oligohaline tidal marshes, were analyzed from monthly collections taken between June 1979 and May 1980. Larvae ofPelastoneurus abbreviatus Loew andThinophilus frontalis Van Duzee, taken from aJuncus roemerianus Scheele dominated marsh, fed predominantly on oligochaetes and nematodes.Pelastoneurus abbreviatus, collected in a nearbySpartina cynosuroides (L.) Roth marsh, also fed on oligochaetes but consumed more polychaetes than nematodes. By being predators and prey in turn, these larvae serve in the transfer of energy between benthic, aquatic, and terrestrial components of the marsh, system.
