Buzzers trout flies are a midge pupa and are so called because of the buzzing noise they make in swarms. Buzzer Trout Flies start in life as a blood worm and live in the mud usually in still waters, they are generally red in colour at this stage although close to hatching the colour of the buzzer fly fades, The buzzers will then travel to the surface of the water in a wriggling action once they are there they will wait before hatching and so quite often drop back down a few times, this is a great period for the trout to feed on buzzer flies. Keeping the buzzer quite still then slowly retrieving then letting it stay motionless again will imitate a natural hatch. When the buzzers eventually hatch they will come out in adult buzzer for or midge flies. The life cycle of buzzer flies is really quite easy and they do hatch all year round, keep a look out for the adult for of the flies or discarded pupa bodies.
