Small but not forgotten. Midge can be an important food source for trout and at times they key in them and eat them by the dozen. Midge live as a larvae in the water, but hatch every year and in this process become vulnerable to the trout at all levels of the water column. A Chironomid is the aquatic larvae or pupae state of a Midge and can be fished under a strike indicator, intermediate sinking line, or suspended under a dry fly.
