Trends
This species has always been restricted in our area to Jersey, where it was discovered in 1872. It was long thought to be an extreme rarity, but its habitat requirements were not understood until the late 1950s. It was then discovered in a number of sites on the west and south coast of the island.
World Distribution
Mediterranean-Atlantic element, reaching its northern limit in Jersey.
