| Shaw & Ford (1991): Anarta myrtilli (L.): 1 male, 5.vii.78, 19.vii.78, Surrey (M.R.S.). This specimen was determined by Dr Herting and is the first record of impressa from Britain. |
| Belshaw (1993): Hosts: in Britain Anarta myrtilli (Lepidoptera: Noctuidae) (Ford & Shaw, 1991 -determined by B.Herting). In Europe single records from the above host and the non-British Sidenidis anapheles (Nye) (Noctuidae) and Rhypania purpunata (L.) (Lep.: Arctiidae).
British distribution: S.England (Linwood in Hants 30.viii. 1971 NHM; Bagshot Heath in Surrey 20.viii.1934 NHM; Bexley in Kent 1971 NHM), probably wider (only recently recognised as occurring in Britain). |
| Tschorsnig (1994): Europe to Scandinavia; NS NW BY NB / A. Data of finds from Mid June to Mid August (in Southern Europe from End April to Early September). Rare (commoner in Southern Europe). Anarta myrtilli L Leucania evidens Hueb. (Noctuidae); Rhyparia purpurata L. (Arctiidae). |
| JNCC Calypterate Review (1996): DISTRIBUTION Hants (Linwood, 1952), Kent (Bexley, 1911), and Surrey (1978, in Ford & Shaw 1991; Bagshot, 1934) (Belshaw 1993, where the 1911 and 1952 records are inadvertently given as 1971).
HABITAT Heathland.
ECOLOGY The larvae are parasitoids of Anarta myrtilli (Lepidoptera, Noctuidae), a heathland species with caterpillars that feed on Heather. Adults in August.
STATUS Although only recently recognised as British (Ford & Shaw 1991), this is undoubtedly a scarce species.
THREAT Conversion of heathlands to forestry plantations; the encroachment of residential building and of commercial and industrial development.
MANAGEMENT Conservation of the declining heathlands in the south of England; maintain a mosaic of vegetation types and encourage the growth of Heather, using rotational burning if necessary to prevent scrub invasion. |

collection has it and which draw/column it is in. Status is taken from the JNCC
Calypterate Review (1996) and the JNCC Recorder package (1997). Synonyms were
taken from a number of sources but most notably the most recent Checklist of
British Diptera by Peter Chandler. |
