Shore flies resemble eye gnats, fruit flies, or vinegar flies in general shape.
Shore flies are sometimes confused with darkwinged fungus gnats which are about the same size and color. Egg - Shore fly eggs are about 0.42 long and 0.2 mm wide. They are fairly rounded at both ends although there are small lobes on one end. The surface of the egg is covered with minute, faint polygons. The eggs remain white throughout the development of the embryo.
