Macro-moths 2006

by Melissa & Andy Banthorpe

INTRODUCTION

In contrast to 2005, the year 2006 was very good for moths in the county. There were three new county records – Valerian Pug, Delicate, and Ni Moth. The two latter species are migrant moths, and this year was an exceptional year for migrants in the United Kingdom with several different species having been recorded. In the county we had our fair share of migrants with 15 species recorded. In particular Scarce Bordered Straw did exceptionally well, with 35 individuals seen. This species had previously been recorded only once before, in 1974.

The previous recorder, Les Hill, resigned in October 2006 as he was moving to Dorset to take up a post as part of the new National Moth Recording Scheme. He handed on to us a comprehensive Mapmate database containing many of the county’s records and helped with  the transfer of this and the many queries that followed. We have added all the remaining 2005 and 2006 records and have commenced work on checking and transcribing the records held at Bedford Museum, which are mostly from the 1980s and 1990s.

Our interest in moths was inspired by trapping with the former county recorder Vic Arnold and we are grateful for his assistance with the assessment of some of the historical records. Latterly we have run a trap regularly in our garden since 2003 and have spent many evenings out and about with Colin Plant and the Herts Moth Group. We would like to acknowledge the assistance given to us by David Manning and Charles Baker, and also Ian Woiwod who has helped immensely with the provision and interpretation of data from the Rothamsted Insect Survey (RIS) traps in the county. Andy has attended a moth genitalia dissection course with Jon Clifton of Anglian Lepidopterist Supplies, and is happy to deal with any macro-moths that need to be determined by this method.

A short note with respect to county boundaries and recording jurisdiction: County Moth Recorders around the United Kingdom use the Watsonian Vice-county boundaries to record, Bedfordshire being VC30. These boundaries remain static and will never change. With the digitisation of maps it is now much easier to ascertain where the VC30 boundary departs from the Bedfordshire administrative boundary than it was at the time that Arnold et al. (1997) was written. Hence as recorders we will be concentrating on recording within the VC30 boundary though we will be very happy to receive all records from within Bedfordshire, passing on those that fall outside the VC30 boundary to the relevant recorder, whilst retaining a copy on the county database. Significant records from outside the VC30 boundary but within Bedfordshire administrative will be listed below, separately from the other records. 

REVIEW

The following lists species recorded in Bedfordshire during 2006 with a UK status of Notable (Na or Nb), Red Data Book (RDB), UK Biodiversity Action Plan (BAP) Priority Macro-moths, migrants, vagrants and accidentals, plus some noteworthy records.
Please note the species status, in square brackets, refers to the national status and in some cases does not refl ect the status in Bedfordshire or VC30. A list of the macromoths of VC30 with their current status is on the Beds Moth Group website (www.vc30moths.org.uk) or available from the Recorders on request.

Sesiidae
370 Hornet Moth Sesia apiformis (Cl.) [Nb]

Lasiocampidae

1633 Small Eggar Eriogaster lanestris (L.) [Nb]

Since then it has consistently been recorded, primarily in the east of the county.
1715 Plain Wave Idaea straminata (Borkh.) [Local]

From 1969 to 1973 it was regularly trapped in the Sandy I RIS trap, but it was then not recorded until 1981 in King’s Wood Heath and Reach. There have been occasional records since then from various sites and the species was last recorded in 2003.

2291 Coronet Craniophora ligustri ([D.&S.]) [Local]
Studham 3rd July (CBa). The first reliable modern record since 1917, as B.B.West subsequently regarded his record of this moth in 1957 as possibly having been recorded erroneously.
2321 Dark Arches Apamea monoglypha (Hufn.) [Common]
Lower Stondon 28th Oct, a very late record, probably from a second generation (AMB&MGB). There is a later record on 16th Nov 2004, but generally the fl ight season ends in late August.
2333 Large Nutmeg Apamea anceps ([D.&S.]) [Local]

2360x Ear Moth Agg. Amphipoea oculea Agg.
There were six records this year of ‘Ear Moths’ from Kempston, Potton, Sandy RSPB, and Stotfold. All are extremely likely to be Ear Moth, Amphipoea oculea, as the habitats for the other three ‘Ears’ do not occur in the county. However, to be sure the moths would have had to have been dissected. As the specimens were not kept this was not possible. At some point it would be good to confirm which species of Ear/s do occur.
2368 Crescent Celaena leucostigma (Hb.) [Local]
This is a very scarce moth in the county. It has previously been recorded only fi ve times in the county – in 1965 and 1966 in Bromham, 1974 in Sandy II RIS and Shuttleworth RIS, and in 2004 in Eaton Ford. In 2006 it was again recorded in Eaton Ford on 23rd July (AL).

BEDFORDSHIRE RECORDS FROM OUTSIDE VC30
The following significant records were recorded from a site in Bedfordshire administrative but in the Vice-county of Hertfordshire (VC20):

Geometridae
1748 Beautiful Carpet Mesoleuca albicillata (L.)
Great Bradwin’s Wood 17th July (CBa).
1885 Clouded Magpie Abraxas sylvata (Scop.)
Great Bradwin’s Wood 17th July, more than ten (CBa). This species had not been recorded in Bedfordshire since at least 1970. It is hoped that a site for it can be located within the Vice-county.

Migrant records are forwarded to the appropriate editor for inclusion in the Immigration of Lepidoptera to the British Isles Report for the Entomologists Record and Journal of Variation. All records are held by the Bedfordshire and Luton Biodiversity Recording and Monitoring Centre and updated regularly.
 

PREVIOUS FIRST COUNTY RECORDS
The following first county records have not been published before and have been noted here for completeness.

Arctiidae

2043 Orange Footman Eilema sororcula (Hufn.) [Local]
Maulden Wood 31st May 2003 (CWP).

Noctuidae

2236 Pale Pinion Lithophane hepatica (Cl.) [Local]
Sandy RSPB 28th March 2003 (MG). This species was reported as occurring in Bedfordshire by Heath and Emmet in 1983. However, J.Heath, in a personal communication to V.W.Arnold mentioned in Arnold et al. 1997, considered this record to be erroneous.
