Ynghylch

The Norfolk hawker is a large hawker dragonfly that is on the wing for a short period during June and the very beginning of July. A rare dragonfly, it is mostly found in the marshes, fens and ditches of the Broads National Park where water soldier is growing. It needs unspoilt grazing marsh with non-saline water to survive. Having spent up to two years in the water, mature dragonfly larvae climb on to emerging vegetation at night and moult into adult dragonflies, leaving behind a cast known as an 'exuviae'. Newly emerged Norfolk hawkers wait until early morning to fly off to other areas to feed, but will take another two to three weeks to reach maturity.

Sut y gall bobl helpu

The Norfolk Broads is an inland waterway and a very special area of fen, marshland and reedbed. Along with the Suffolk Broads, it is the UK's largest protected area of wetland and has National Park status. Many organisations and individuals work together within the Park to conserve and enhance its rare habitats for the benefit of both wildlife and people. Norfolk Wildlife Trust and Suffolk Wildlife Trust are two of these partners and between them have a number of nature reserves in the area, which they protect for local wildlife like the rare Norfolk hawker. You can help by becoming a member and supporting the work of your local Wildlife Trust.
