Abstract:
Results of an eight-year survey of the marsh flies or snail-killing flies
(Sciomyzidae) of Howard County, Maryland are presented. Twenty-four described species in
nine genera have been recorded from this small county in central Maryland. The genera
include Atrichomelina Cresson, Dictya Meigen, Ditaeniella Sack, Euthycera Latreille, Limnia
Robineau-Desvoidy, Pherbellia Robineau-Desvoidy, Sepedon Latreille, Tetanocera Duméril,
and Trypetoptera Hendel. Two new (at the time of collection) state records—Dictya stricta
Steyskal and Tetanocera rotundicornis Loew—were established, and one undescribed species
of Dictya was discovered. Collecting records are included for all species. Biological
information is summarized for each genus.
