1                     INTRODUCTION


The Concolorous moth has a very limited distribution in Britain, but is found in a number of woodland sites in Northamptonshire. The larvae feed on small-reeds (Calamagrostis spp)., and in our woodlands appear to use purple small-reed (Calamagrostis canescens), but will also usethe wood small-reed (C. epigejos) if this is the only species present.  Wood small-reed is often considered to be a weed species in standard woodlands management, and is often removed from plantation areas as it can out-compete the young trees.



2                     CURRENT STATUS


2.1                International / National Status



2.2                Local Status


In Northamptonshire it has been recorded at several woods, including Glapthorn Cow Pasture SSSI and Geddington Chase SSSI.  The County Moth Recorder, J. Ward, has collated records from many of the sites where the moth has been recorded, and these show a steady decline in numbers from being locally plentiful in the early 1990's, to few anywhere since 1996.







4                     CURRENT ACTION


English Nature are overseeing a survey to establish the status of the moth both locally and nationally.
