Midges are inhabitants of the chara-covered bottom; enlarged about 4 times (after Johannsen, Bull. State Museum). Fig. 92.—The eggs of the common large black horsefly on the tip of the bulrush stalk.

Ostracoda (Fig. 94), which are small bivalved forms resembling the bivalved Mollusca. They form food for fishes to a small degree. Especially abundant just under the chara are the red water-mites (Limnochares aquaticus) (Fig. 80, p. 130). One sees numbers of these.
