IMMIGRATION OF LEPIDOPTERA TO THE BRITISH ISLES IN 2001
STEVEN NASH1 AND BERNARD SKINNER2 1 23 Henley Drive, Highworth, Wiltshire SN6
7JU. (firstname.lastname@example.org)2 5 Rawlins Close, South Croydon, Surrey CR2 8JS.
Formally accepted records of immigrant Lepidoptera occurring in the British
Isles during the year 2001 are listed and discussed. For less frequently encountered
species full information is given; for common immigrants a selection of the
more important records is presented.
NOTES ON PIERIS NAPI (L.) SSP. THOMSONI (WARREN)
AB. FASCIATA (MULLER AND KAUTZ) AND F. FLAVA (KANE) (GREEN VEINED WHITE)
RUPERT BARRINGTON 18 Codrington Road, Bishopston, Bristol BS7 8ET
Breeding experiments with Pieris napi thomsoni have shown the genetic basis
behind both the pattern variation ab. fasciata and the ground colour variation
f. flava. The possible ecological roles of both variations in wild populations
are discussed. These may involve both thermoregulation and visual signalling
in the ultraviolet range.

As part of the National Macro-moth Recording Scheme planning project, a consultation
questionnaire was sent to all county moth recorders in Britain during 2004.
Over two-thirds of county moth recorders responded and the findings are reported
here. The results provide an insight into the current status of the county
moth recorder network, three decades after its inception.
REDISCOVERY OF EARINUS TRANSVERSUS LYLE (HYM.:BRACONIDAE:
AGATHIDINAE), A PARASITOID OF TRICHOPTERYX POLYCOMMATA (D.&S.)
(LEP.: GEOMETRIDAE: LARENTIINAE)
MARK R. SHAW National Museums of Scotland, Chambers Street, Edinburgh EH1 1JF.
Recent rearings of Earinus transversus Lyle (Hymenoptera: Braconidae: Agathidinae),
a probably host-specific parasitoid of the threatened moth Trichopteryx polycommata
(Lepidoptera: Geometridae), are reported from Britain. This braconid wasp should
be seen as an important conservation target as it had not been recorded anywhere
in the world since being described from unprovenanced (presumably British)
specimens more than 100 years old.
DIALECTICA SCALARIELLA (ZELLER, 1850) (LEP.:
GRACILLARIIDAE) NEW TO THE BRITISH ISLES
DAVID J.L. AGASSIZ The Natural History Museum, Cromwell Road, London SW7 5BD.
Dialectica scalariella (Zell.) is added to the British list of the strength
of a specimen taken in Kent in September 2004, details of life history and
distribution are given.
SYNTHYMIA FIXA (FABRICIUS, 1787) (LEP.: NOCTUIDAE) — A
RE-APPRAISAL OF ITS STATUS ON THE BRITISH LIST
R. J. HECKFORD 67 Newnham Road, Plympton, Plymouth, Devon PL7 4AW.
Hitherto in the British Isles, Synthymia fixa (Fabr.) (Lep.: Noctuidae) was
known only from one specimen, and doubts have been expressed about this record.
A second specimen has now been discovered, taken in the same year and at the
same locality as the first. The status of the species on the British list is
discussed. Synthymia fixa is rightly included on the British list, albeit as
ELACHISTA NOBILELLA ZELLER, 1839 (LEP.: ELACHISTIDAE),

PO4 0NY.2 The Natural History Museum, Cromwell Road, London SW7 5BD.
Changes in the list of British microlepidoptera since 2000 are given. These
comprise 17 species where research into type material or early literature has
led to a change in the specific name. Additions to the British fauna are also
listed. These are made up of 14 species newly discovered in Britain, six adventive
species and species added on account of species splits or changes of status
to specific rank. Four further additional taxa are mentioned which have been
reported in the literature, but which require further research before formal
addition to the checklist.
OCCURRENCE OF THE EUCALYPTUS PSYLLID CTENARYTAINA

The eucalyptus psyllid Ctenarytaina eucalypti (Maskell) (Hom.: Psylloidea)
and its parasitoid Psyllaephagus pilosus Noyes (Hym.: Encyrtidae) are reported
from the Isle of Man. The source and mode of entry of P. pilosus and its distribution
in the Isle of Man are discussed.

Elachista regificella (Lep.: Elachistidae) was recently shown to be a species
complex. In this paper the occurrence of the three constituent species, E.
regificella Sircom, E. geminatella (H.-S.) and E. tengstromi Kaila et al.,
in Britain, is outlined. Diagnostic characters are given for each species.
Life history records indicate that the species have, at least to some extent,
different host plant preferences: Luzula sylvatica is recorded as the host
plant of E. regificella and E. geminatella, the latter probably exploiting
other host plants as well. L. pilosa is the only known host plant of E. tengstromi
THE USE OF COUNTRYSIDE STEWARDSHIP SCHEME FIELD MARGINS
BY THE SMALL SKIPPER THYMELICUS SYLVESTRIS (PODA), ESSEX SKIPPER THYMELICUS
LINEOLA (OCHS.) AND LARGE SKIPPER OCHLODES VENATA (BREM. & GREY)

Abundance of Small Skipper Thymelicus sylvestris, Essex Skipper Thymelicus
lineola and Large Skipper Ochlodes venata adults was monitored at three farms
in Essex between 1997 and 2000 and again in 2003 on grass field margins of
varying widths. There were significantly more Small Skipper and Essex Skipper
on two-metre wide margins than on non-margin field edges, but there was a significant
reduction over time in abundance of both these species and Large Skipper Ochlodes
venata on the two-metre margins. When the six-metre margins and the control
sections were compared there was no significant difference in abundance on
them for the three species. A lack of nectar sources, the use of agricultural
cultivars of common grasses, inappropriate management and the small size of
some of the margins are suggested as reasons for the lack of abundance.
IN LAPPLAND, JUNE & JULY 2004
A. J. PICKLES 2a Park Avenue, Lymington, Hampshire SO41 9GX firstname.lastname@example.org
I am standing on a boggy path between two stands of Bottle-brush Spruces clutching
a net with a four metre handle. The water is just above the ankles of my Wellingtons
and a cloud of mosquitoes buzz round my head, kept at bay by deet formulated
spray which I have applied liberally to my skin and the rim of my hat. It is
just gone midnight and broad daylight as I wait, fired up with adrenaline,
for the next Xestia skraelangia to dash wildly across the open space between
the trees. Here comes one! A small black Swedish meatball of a moth against
the sky zigzags at what seems like three hundred miles an hour and then disappears
against the foliage before I can make more than two clumsy steps in its direction.
I can't remember when I have had more fun trying to catch moths!

Eurydema ornatum (Hemiptera: Pentatomidae), a species previously unknown from
the British mainland other than as an accidental importation, is reported from
Portland Bill, Dorset, in May 2005. In the light of this two earlier records
are confirmed. It seems likely that this species is now established on the
south coast of England. The status and identification of this and related species
is discussed and a key to the species of this genus occurring in north-west
Europe, which includes other potential future colonists of Britain, is provided.

A STUDY OF THE HIBERNATION BEHAVIOUR OF HYPENA
ROSTRALIS (L.) (LEP.: NOCTUIDAE) – THE BUTTONED SNOUT MOTH
1R.G. FIELD AND 2G. WATKINS 1 166 Sherwood Avenue, Northampton NN2 8TE (E-mail:
firstname.lastname@example.org) 2CERA, Writtle College, Writtle, Chelmsford, CM1 3RR
The behaviour of Hypena rostralis prior to, during and after hibernation was
studied in a wild population and in captive stock. The process of going into
hibernation appeared to have two stages, the first at the end of September
when movement in and out of the hibernation site still continued and a second
in late November when the adults began to settle down. By early December they
had become inactive and remained in this state until March or early April when
movement started again. They left the hibernation sites by 26 April. The movement
seems to be triggered by day length rather than temperature. The use of buildings
may be atypical and natural sites may be favoured.
MONITORING GLOW-WORM LAMPYRIS NOCTILUCA L.(COL.:
LAMPYRIDAE) POPULATIONS IN GRAZED AND MOWN GRASSLANDS
TIM GARDINER AND MICHELLE GARDINER Centre for Environment & Rural Affairs
(CERA), Writtle College, Lordship Road, Writtle, Chelmsford, Essex, CM1 3RR
Glow-worms Lamyyris noctiluca L. (Col.: Lampyridae) were studied in grasslands
under varying management regimes. Meadows subjected to a single summer cut
for hay supported smaller colonies than unmanaged sites although the reasons
for this are unclear. Grasslands mown regularly throughout the summer showed
an increase in numbers of females; it is theorised that this might be a consequence
of favourable adjacent habitats and that the shorter sward provided advantage
to females displaying to males in flight overhead. A mosaic of regularly mown
and tall unmanaged grassland may provide the ideal habitat. Grasslands subjected
to grazing by cattle or rabbits supported only small colonies.
