(7) Treats of Trout
Taeniopteris nebulosa is one of the first signs of the spring on the Tainionvirta river. On a warm day in March, dozens, even hundreds can eclose, or hatch, and start crawling on the snow or buzz on the surface of the water. Newly eclosed taeniopteris are brownish in color and their clumsy movements on the water entice trout to attack. The trout consider taeniopteris a delicacy, and fish start swimming from lake Jääsjärvi to the river on warm days in March tempted by the insect. The fishermen make the teaniopteris their model when they design their fishing flies.
