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.

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

The UK Butterfly Monitoring Scheme (UKBMS)
UKBMS report for 2019 is now available.
Click here to download from our website or

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%.

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
Wider Countryside Butterfly Survey
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

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.

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.

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.

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.

2019 is the final year of
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.

The Marbled White has had a 111% increase but still not crossing the
border into Suffolk.

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
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
White Admiral and
Marsh Fritillary show few signs of stopping.

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
