Range & Status
A widespread species in Europe, but largely found in southern Britain. Very local, probably increasingly scarce through habitat degradation and loss, but also probably underrecorded.
Old reports from the Lizard and West Penwith, but only recently found on Carvear Moor, St. Blaise, in 1991 and Colvannick Pond, Bodmin Moor in 2004. Probably many more sites await discovery.

Drainage and infilling of wetlands.
Protection of old wetlands is required.
