SUFFOLK  COUNTY  BUTTERFLY  RECORDER

The post of County Butterfly Recorder will become available at the end of 2020 when the present Recorder, Bill Stone, retires from the role.

The post is a Suffolk Naturalists’ Society position, and anyone wishing to receive further details of the role should contact:

Martin Sanford, Chair, Suffolk Naturalists’ Society
martin.sanford@suffolk.gov.uk

Or Peter Maddison, Chair, Suffolk Branch of Butterfly Conservation
prmaddison@yahoo.co.uk
01473 736607

The Recorder’s role is to encourage accurate recording of butterflies in Suffolk, to verify and keep county butterfly records and to produce an annual butterfly report for publication in the Suffolk Naturalists’ Society Transactions and the Suffolk Branch of BC Argus.

In order to promote butterfly recording the Recorder has to be able to engage with a wide range of stakeholders, wildlife groups, individuals, and an enthusiastic group of butterfly recorders (approximately 70 individuals) within the county. 

Sharing the duties of this role could be considered.

Coronavirus - Butterfly Recording

1st June 2020
Further significant changes relating to outdoor activities have been made to the government restrictions that were brought in March to reduce the spread of coronavirus. Across the UK, the key message remains to stay at home as much as possible and to follow social distancing rules. However, the specific details vary from country to country.

In England and Northern Ireland, it is now possible for butterfly and moth recording to resume for people who are not shielding or self-isolating.

Wider Countryside Butterfly Survey (WCBS)

Over the last few weeks restrictions relating to outdoor activities have been relaxing at varying pace across the different nations of the UK.  We were able to resume butterfly monitoring in England from 14th May  Click here for full details from UKBMS


The WCBS is a national scheme which complements the transects of the UK BMS with mini transects walked in squares randomly selected by the BTO computer.  Volunteers from Butterfly Conservation and the BTO need to walk just twice per year in July and August (with an optional spring walk if you wish).  This means that the commitment is not heavy.

The Wider Countryside Butterfly Scheme (WCBS) Report 2018 has been published.  Click here to download a copy in pdf format.

Over the past nine years volunteers have monitored butterflies in a selection of 1 km squares.  In July and August 2017, on two walks along fixed routes, 774 squares were surveyed nationally, 39 squares in Suffolk.  The Report is an interesting read showing not only the results of butterfly species numbers and analysis,  but also a guide to some day-flying moths which recorders are encouraged to include.    If you have not previously been part of the scheme but would like to become involved in 2018 contact Twm Wade at the email address below.

We have 11 squares in need of a volunteerFor details of the squares click here for the WCBS page

Forest Work at Theberton Woods

Forest England (FE) have notified forest work planned for later this year.  Preliminary work will be necessary to upgrade the turning area to enable modern lorries to manoeuvre.  Forest England is aware of concerns for wildlife, including the Purple Emperors.  The mature oaks favoured by the Purple Emperor will not be felled.  The sallows will not be cut - except where they are obstructing the rides.  The works that are being planned are as follows:

March:
Flail flat (via hedge cutter) all vegetation on the sides and banks surrounding the lorry turnaround thereby allowing Civil Engineering to see the full extent of the turnaround prior to them extending it for full length lorries.  (In the past it was common practice for timber haulage to be undertaken by eight-wheelers.)

April:
Civil Engineering will grade the lorry turnaround and remove all the vegetation and soil from the surface so it does not hold water and allows the road to drain properly.  Crushed stone will then be brought in and laid and allowed to settle prior to use later in the year. 

This summer:
FE will be surveying the wood to look at what areas should be thinned.  There are several stands of oak that may well be included.  The timing of the work is still to be confirmed as there are several European Protected Species within the wood and FE also want to minimise any disturbance or damage to nesting birds.  FE is working closely with Suffolk Biological Records and the County Wildlife Recorders to ensure all of their operations are properly managed.

This Autumn:
It is planned that all timber extraction will be kept off the rides but should there be any damage then this would be reinstated.  The thinning operations will greatly improve the overall habitat of the wood and will also greatly assist natural regeneration. 

Next few weeks:-
Because the contractors have phased out their 8-wheeler lorries, the extraction will be done on longer lorries.  Unfortunately these lorries need more space to turn than is available in the present turning/loading area (known to some as the observation arena for Purple Emperor).  This work will begin in the next few weeks.  The first phase will be the removal of broom, gorse and other scrub obstructing the track into the forest.  It will also entail felling some trees to make space for the lorries to turn.  The difference in height between the forest rides and the turning area will necessitate a ramp.  The whole turning area will be surfaced with crushed stone.  Obviously all this has to be finished before the felling operation can begin.

Forest England is mindful of the presence of Purple Emperors, and intends that there will be no long-term impact on the butterflies.

End June Update- Suffolk Butterfly Recording 2019- "Black-Holes"

This is a map of the Suffolk recording area which shows the areas remaining as at end of June 2019 without any butterfly records i.e. "black-holes" that exist, these are shown by the dark-blue spots.

For a list of the Grid References of the tetrads click here to go to the Black Holes page

Based on the map the following tetrads in the table on the Black Holes page should be visited in order to increase county coverage.  2019 represents the final year of the current five-year recording period for the Butterflies of the New Millennium recording scheme so this is an incredibly important year

Distribution Maps for 2014 to 2018

The latest distribution maps for Suffolk butterflies have now been produced by Bill Stone the Suffolk Butterfly Recorder.  The maps are based on results received during 2014 to 2018 from several sources including those shown on the Sightings Page of this website.  For anyone who has the maps produced 15 years ago* they show significant differences for some species.  For example the Wall is now almost entirely restricted to the coast and the Silver-washed Fritillary was not present in Suffolk.

To see the maps click here

2019 is the final year of the Butterflies for the New Millennium (BNM) recording scheme so every sighting received will contribute to the new Butterfly Atlas which will be produced by Butterfly Conservation.

You can see the UK distibution maps for the most recent five-year survey of the Butterflies for the New Millennium (BNM) recording scheme (2010-2014).  Click here to download the Atlas of UK Butterflies 2010-2014 in pdf format (11 MB).

40 year slump for UK Butterflies

More than three-quarters of the UK’s butterflies have declined in the last 40 years with some common species suffering significant slumps, a major scientific study has revealed.  A number of widespread species such as the Wall, Essex Skipper and Small Heath now rank amongst the most severely declining butterflies in the UK. 

The findings also reveal that intensive conservation efforts have started to turn around the fortunes of some of the UK’s most endangered butterflies. During the last 10 years the numbers of the threatened Duke of Burgundy have increased by 67% and the Pearl-bordered Fritillary has experienced a 45% rise in abundance.  Dingy Skipper and Silver-studded Blue have shown 21% and 19% increases in occurrence respectively and even the UK’s most endangered butterfly, the High Brown Fritillary, has been relatively stable in the last decade.

But despite breakthroughs with some threatened butterflies the report revealed that other species continue to struggle.  The long-term decline of the Wood White, White Admiral and Marsh Fritillary show few signs of stopping.

When to See Butterflies. 

The
Suffolk Butterflies page lists the butterflies that can be seen in Suffolk, shows when you can expect to see them and the foodplants upon which their caterpillars feed.
We can also help if you would like advice about making your garden more attractive to butterflies

See the News page for dates of First Sightings

Like much of the UK, Suffolk's countryside and wildlife are under increasing pressure.  It's a situation that is unlikely to improve in the forseeable future and there's never been a more urgent need to understand and conserve our butterfly fauna.  The county has a gently undulating landscape of surprising contrasts, defying the stereotype of "flat East Anglia and its arable prairies".  The unspoilt coast, intimate river valleys and, especially, the Sandlings heaths and Brecks ensure that Suffolk retains a more varied butterfly fauna than might be expected.

Some recommended books are listed here

 Butterfly Records.
