When the momet is approaching, where the larva becomes an adult, it comes out of the water, climbing on a stick, tree bark, or plant stem. There is also a transformation. Slowly, it breaks in the middle of the trunk, so that it can then emerge from the head first, then the torso with the legs and wings, and after a longer time also the abdomen. On the sides of the skin sometimes you see white threads, that is, the remains of the gills, which in the course of transformation, they line.
