The para midge represents an emerging chironomid or midge. Only the front half of the fly should have floatant applied, so that the front half floats, the back half sinks. The result will be recognized by fish as an emerging chironomid, and an easy meal.
This fly snagged me a solid Brown here in spring on 11 Mile Canyon in Colorado. Notoriously educated and picky fish. So I was excited landing a fish trying this fly on whim. Recommended!
