B&F:
Bradley & Fletcher categorisation, now supeceded by the UK List as per Agassiz,
Beaven & Heckford
ABH:
UK list of lepidoptera authoured by Agassiz, Beaven & Heckford
Status
Defined using one of these four self explanatary terms: Resident, Migrant,
Vagrant or Accidental.
Unknown: Status currently unclear, usually due to lack of modern records
Distribution and Abundance:
Resident status is categorised as follows:
Common: To be found wherever its
food plant occurs plentifully and usually seen in good numbers
annually.
Local: With a distribution more restricted than that of
its food plant, or occurring on a localised food plant.
Scarce: Few modern records.
Rare: Very few modern records.
Migrant, Vagrant or Accidental
status is categorised as follows:
Common: Seen annually, sometimes
in good numbers.
Irregular: Seen less frequently and not every year.
Scarce: Few modern records.
Rare: Very few modern records.
Primary Habitat:
Where the moth is most numerous, or for less well recorded
species where it has occurred the most.
Flight period:
Number of annual broods and months when it is mainly seen on the
wing.
Localities and Records:
Up to four recent localities are specified for local species.
Full records to a maximum of four are referenced for scarce and
rare species.
Observations:
General observations, notes and information. Includes information on natural
variation, melanism, forms, or other relevant information.
Confusion Species:
Similar species, or groups of species, which can cause confusion in identification. Note that some moths require detailed examination (often using microsciopical techniques) to be sure of identification.
