An extremely rare moth found only in Essex is making a comeback.
The resurgence of the Fisher's Estuarine moth comes after seven years of work between conservation organisations in the county.
Surveys have shown they are now being found in locations outside of their normal home on Skipper's Island in the Walton backwaters.
The moth is limited to where it can live based on the presence of the caterpillars' sole food plant – Sea Hog’s fennel. Conservation efforts have focused on settling the plant in areas not at risk of flooding.
