Peter D. Stilling, Donald R. Strong

Abstract


The shore fly, Hydrellia valida Loew (Diptera: Ephydridae), commonly mines the leaves of salt marsh cord grass, Spartina alterniflora Loisel, at Oyster Bay, northwest Florida. Its larvae are frequently parasitized by Opius sp. (Hymenoptera: Braconidae), and sometimes by Pteromalus sp. (Hymenoptera: Pteromalidae) and Sympiesis sp. (Hymenoptera: Eulophidae).
