Crambus uliginosellus

A very rare and probably under-recorded species in Somerset, currently known from just two sedgey mire sites on Exmoor with particularly liquid mud - the kind of sites that hold decent populations of Keeled Skimmer Orthetrum coerulescens.  There are probably further sites to be found on Exmoor, and possibly on the Quantocks and Blackdowns (where it was recorded in 1915).  It is not exclusively an upland species; a 1922 record exists for Shapwick, and it still occurs in lowland Devon.
