Notes: The Saint Mark's fly (Bibio marci) appears around the 25th of April and flies for about two weeks. Strictly speaking, it is not a water insect. It happens though that its life cycle takes place very close to rivers and streams. They fly in swarms of hundreds or thousands of specimens that mate in flight. Because of the frenzy, error of trajectory or just because of the wind, it happens that they end up in the water quite often. And the fish never miss the opportunity.
