Sector The Wildlife Trust
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 Reed (Calamagrostis spp)., and in our woodlands appear to use Purple
Small-Reed (Calamagrostis canescens), but
will also use the 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.

CURRENT
STATUS
2.1
International
/ National Status
·
Red Data Book status: rare.
·
In the early 1990’s colonies were known in
fifteen 10km squares. There is now
evidence to suggest that this may overstate the present position.
·
Recent surveys have failed to find the moth in
some of its former Northamptonshire strongholds. Some of the last records from other counties well predate the
decline in this county.
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.

CURRENT
FACTORS CAUSING LOSS OR DECLINE
·
Habitat loss
·
Scrub encroachment.
·
Removal of Calamagrostis
spp. from plantations.
·
Changing climate. The keeper at Geddington Chase, a site where there have been no
records of The Concolorous moth since 1997, has observed that the wood is
becoming wetter overall, but drier in the summer. This observation is confirmed by the keeper at Salcey Forest and
by one of the rangers at Fineshade.

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