Moths of Dungeness and Surrounding Area
 

  definitions we have used for
  Area Status 

  Common Resident. Breeds,
  sometimes abundantly and in
  large numbers.

  Resident. Regular breeder.
  
  Scarce Resident. Breeds in the
  area in small numbers or
  infrequently.

  Migrant. Regular immigrant, 
  may sometimes breed.

  Scarce Migrant. Known
  immigrant species, recorded
  less frequently than Migrant.
  
  Vagrant. Vague category, not
  known to breed in the area nor a
  known migrant. Of irregular
  occurrence.

  in J.D.Bradley, a Log Book of
  British Lepidoptera 2000, the
  word sporadic is used, with, and
  sometimes both migrant and
  vagrant, to describe status. The
  Kent list uses Migrant for all
  known migrant species.
  
  The last three categories, by
  definition, all involve immigration
  into our area. Known migrants
  are more clear cut; we have
  used Vagrant to mean a species
  that hasn't been proven to breed
  and occurs so infrequently,
  or could not breed because of the
  absence of the larval foodplant.

SYSTEMATIC  LIST

In 2001, sponsored by Dungeness Bird Observatoy and British Energy, we
published a guide to the status and distribution of Moths of Dungeness and
Surrounding Area. This brought together records past and present and
offered information on earliest and latest dates recorded and the maximum
number recorded at one trap-site on one night. An attempt was made to
present, in table form, all our records so that the reader could define their
own categories.
We defined Scarce Resident as occurring on 1-15 dates at one or more trap
sites on one or more of the years in the survey period. As a Resident on
15-40 dates and Common Resident on over 40 dates. As with all attempts to
categorise, exceptions and grey areas and controversy will exist.

These web pages are a long term project to review and update what we know. The Guide, which 
includes more details on the conventions used, is available on request.

Pictures are of moths caught in the area.

To the left are the yearly date counts. Since 2000 the number of recorders has increased. For species
recorded on more than twenty dates only the totals for the trap-sites in the Guide are shown to try and
maintain a common base for comparison. All dates are given for species recorded on less than ten 
dates.
Whether a species has been recorded at a site is shown to the right.

We have also been able to extract from the data collected from the sites of Barry Banson (off shingle site)
and David Walker (on shingle site)  trends showing the fortunes of the commonest 110 species that occur
in our area.

Eyed Hawk-moth to Heart and Dart
Crescent Dart to Southern Wainscot
Smoky Wainscot to Dingy Shears
Lesser-spotted Pinion to Beautiful Golden Y
Plain Golden Y to Olive Crescent and additions

Pyrals

making sense of the left column of figures for each species page ...
Number of traps each year .. in 1990 there were 3 traps in 1991 and 1992 there 
were 5 traps, in 1993 there were 7 traps, in 1994 to 2000 there were 8 traps ..
The last few years the number has grown to 16. Were we to include the number 
of nights from the new traps, many species would show a dramatic increase in 
frequency. The figures in the left hand column for the vast majority of species 
are from this base-line of sites. Bearing this in mind, any apparent increase 
90 to 92 is usually as a result of increased coverage, unless otherwise indicated.

  In 1998 Ian Ferguson, as Moth
  Officer for the Kent branch of
  Butterfly Conservation, took over 
  the county recording of moths from
  Eric Philp.

  Since then Ian has produced an
  annual report and also a check 
  list (provisional) of the moths
  recorded in Kent. His categories
  he ascribes to Parsons 1984 for
  micros (number of records at
  Vice-County level) and Waring 1999 
  for macros (10k squares).

  RDB1.  Endangered.
  RDB2.  Vulnerable.
  RDB3.  Rare.
  Na and Nb.  Noteable.
  Common.
  Local.

  Although the two definitions, for 
  Area and Country, are not directly
  comparable, they give an indication
  of how moths recorded here fit into
  the bigger picture.
