The Serratella ignita is one of the classic mayflies for the sommer months, whose imitation can become very handy
for any fly angler in Europe. It is widely spread throughout the continent and it hatches often in abundance.
Furthermore, if there was a scale of preference for what fish like to feed on -
and I assume that fish must have a sort of taste sense - , I would
surely put the BWO dun at second place of such hypotetycal ranking list.
