The insect population thrives in the abundant aquatic and bank vegetation. Hatches of sedge, mayflies, stoneflies,
sialidi, but also terrestrial falling into water from the surrounding grass, provide the trout with abundant food.
In the image on the upper right corner a Siphlonurus armatus, a mayfly that along with Serratella and small olive Baetidi has offered the most interesting hatches during our
visit in early June.
