Sunday 18th April 2021 - Spring Scything Experience, Landseer Park.
1st of two introductions to scything with traditional scythes.

This is planned to take place but will be limited to 5 people as per Coronavirus regulations in force on the 18th April.  This will also be socially distanced.
It is essential to contact Julian - details below.

This taster session on the techniques of cutting wildflower meadows and grasslands with scythes will also benefit butterflies, moths and bees.  Not only will you learn how to scythe but we will also explain why this old method of managing grasslands is exceptionally good for our native wildlife.

This first event is at the Spring Equinox, just as the grass has begun to grow.  Scything is simple, enjoyable and suitable for anybody.  Modern scythes are also very lightweight and easy to work with. 
There will be another event in late summer (9th Aug) if you can’t attend this one.


Bring your own lunch and suitable sturdy, waterproof footwear.  We will provide the scythes but please book in advance as there are limited places.
Where: Landseer Park

PHOTOGRAPHIC COMPETITION FOR SUFFOLK BRANCH MEMBERS

Results

The Suffolk Branch Photographic Competition, held in Feb/Mar this year was a success with 80 photographs submitted by our members.  Unfortunately, Covid restrictions dictated the cancellation of the 2020 AGM, so our members didn't get to view the entries as usual in person.  We trust that this online alternative was a more than suitable alternative. 

A large number of the entries received votes and we are pleased to announce that the results are

First - Entry 66; Hummingbird Hawkmoth, Kessingland, Suffolk; 25 Jun 2020 - photo by David Borderick

Second (joint) - Entry 15; Common Blues, Abberton Reservoir, Essex; 13-Jul-2020 - photo by Paul Claridge
Second (joint) - Entry 35;Wall Brown Carlton Marshes, Suffolk; 25th May 2020  - photo by Robert Quadling

Third - ENTRY 8; Swallowtail; Wheatfen NR (Ted Ellis Trust), Norfolk; 29 May 2020 - photo by David Pitt

The standard of entries was very high, making it a closely run vote. Thank you to everyone who took part. We look forward to your photographs from 2021 when our competition returns next time.

NEW SUFFOLK  COUNTY  BUTTERFLY  RECORDER

The new County Butterfly Recorder for Suffolk is James Corton.  He takes over from Bill Stone. 

The post is a Suffolk Naturalists’ Society position but works closely with Suffolk Butterfly Conservation.

COVID restrictions mens they have been unable to meet so they are going to start a series of Zoom calls in order to make progress with getting James familiar with the various databases and recording schemes.  Bill will support James until he feels confident to assume the role fully and Bill will also help him with the 2021 report

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.

James can be contacted at

The Wildlife Garden at Aldeburgh

This book is the story of a remarkable and enduring transformation.  When Trudie Willis and her husband David moved to Priors Oak, alongside the Aldeburgh to Leiston road, they were faced with unpromising sandy soil.  Now the garden has grown to ten acres of ferility and abundance.  It offers a wide range of attractions, from the more formal areas to productive vegetable beds, with donkeys and tortoises along the way.  At the far end, an extensive wildlife garden has yielded a long, varied and increasing list of species.  For many years, Trudie has opened her garden to visitors, suppoting a wide range of charities and raising well over £50,000.

The text and general photos are by Richard Stewart, with many extracts from Trudie's own garden notes.  Richard was the former Suffolk Butterfly Recorder.

Liz Cutting has provided the species photos and she also worked with Richard on his last book 'The Butterflies of Christchurch Park'.  Her photographs have appeared in many publications and she is one of Suffolk's leading dormouse experts.

The book can be purchased, price £7.50, from the author at 112 Westerfild Road, Ipswich, IP4 2XW. 

Also at one of the garden open days - details at Priors Oak Butterfly Garden (google.com)
One of these open days is on Sunday 1st August when Butterfly Conservation will be present.
See Butterflies at Priors Oak - Priors Oak Butterfly Garden (google.com) for photographs from previous years.

All profits will go to the work of Butterfly Conservation in Suffolk.

The UK Butterfly Monitoring Scheme (UKBMS)

The UKBMS report for 2019 is now available.  Click here to download from our website or click here to download a higher resoltion version from the UKBMS website

In the UK Butterfly Monitoring Scheme (UKBMS), annual data on the population status of butterflies is derived from a wide-scale program of site-based monitoring and sampling in randomly selected 1km squares.

The sampling framework comprises: (1) Weekly butterfly transects (Pollard walks); (2) Reduced effort surveys of habitat specialist species (including timed counts of adults, single species transects, and egg and larval counts); and (3) the Wider Countryside Butterfly Survey (WCBS).

The resulting UKBMS dataset is one of the most important resources for understanding changes in insect populations and answering policy questions relating to status and trends in biodiversity.

The data is used in the recently published National Statistics UK Biodiversity indicators.  This release and publication report on UK progress towards meeting the biodiversity goals and targets ‘the Aichi targets’ agreed in 2010.  Key results Since 1976 show that the unsmoothed habitat specialist butterflies index has fallen by 59%.  Over the same period, the unsmoothed index for species of the wider countryside has fallen by 20%. Click here to download a copy.

The UKBMS scheme has monitored changes in the abundance of butterflies throughout the United Kingdom since 1976. Forty years later, trends in butterfly populations were compiled from a network of over 4,000 locations across all years, with nearly 2,500 sample locations monitored in 2015. The UKBMS is based on a well-established and enjoyable recording method listed above and has produced important insights into almost all aspects of butterfly ecology.

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 2019 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 volunteer.  For details of the squares click here for the WCBS page

New website for Suffolk Moths

Butterfly Conservation is for moths as well as butterflies.  There is now a new website with comprehensive information about the moths of Suffolk with photographs, distribution maps and latest sighting dates.  You can submit your own moth sightings as well.

Have a look at the new site here www.suffolkmoths.co.uk

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.

The Branch is always grateful for butterfly records and a recording form can be downloaded from the recording page of this website.
