The Great red sedge (Phryganea grandis), photographed in a flooded quarry.
The Great red sedge wiil eventually transform from this larva, to a moth like brown coloured insect with hairy wings. The insect lives for about 1 year as a larval stage in the water, whereas the winged adult may only survive a few weeks above water. The larva makes a tube made from plant material, from which it gains protection.
