Sedge Larva or Caddis Pupae Flies
The sedge originates from the fact that adult Caddis flies can often be found clinging to sedge grass near the waters. The Latin name for this group of flies is ‘Trichoptera’. They pass through four stages in their development; egg, larva, pupa and adult. There is often confusion between caddis pupae and sedge pupae or caddis larvae and sedge larvae, they are the same thing! Flies work for all sedges.
The eggs hatch into sedge larvea in about 10-12 days. The Larvae produce a sticky substance and attach what ever material in on the river bed to their body. This offers protection and camouflage. The sedge pupae stage lasts for several days. The fully formed caddis pupae has middle body legs that it uses to swim to the surface to hatch. Some species choose the shore or vegetation to emerge rather than open water as there they are easy prey for the trout. Sedge pupae flies work well for trout that see the larvae as a substantial meal on the bottom of the rivers.
