A.G.M & Members Meeting.
THIS WILL NOW TAKE PLACE VIA ZOOM - Instructions below
We have decided that, because of the
continuing relatively high levels of Coronavirus, we cannot hold a
meeting in a closed space. The AGM will therefore be via Zoom
(instructions on how to join below).
The afternoon will start with a short AGM.
The Chair’s Report for 2021 is printed within the Autumn Argus.
Guest speaker - Martin Warren,
Head of Development
at Butterfly Conservation Europe and previously Chief
Executive of Butterfly Conservation.
Martin is the author of the recently published book ‘Butterflies:
A Natural History’ (British Wildlife
Collection). It is
a unique take on butterfly behaviour and ecology. It explores
the secret lives of our British species (also drawing on comparative
examples from continental Europe), revealing how they have become
adapted to survive in such a highly competitive natural world.
The book is available from most booksellers but
more detail is available at the nhbs website here
It was reviewed
by Bob Gibbons, British Wildlife 32(8), August 2021
everyone is likely to learn something from the book, and for me, at
least, it already informs and enhances the way I look at butterflies
when I am out in the field. I should also add that it is well and
clearly written in an easy and open way, with enough personal anecdote
to lighten it yet not so much as to reduce its erudition"
Martin's talk will last about one hour.

AGM can be downloaded as either a

the extraction of timber at Theberton Wood were explained in an
article by Steve Whall, Forester for Forest England, in an article published in

In brief, after a meeting of
concerned parties, it was arranged that in the late Spring / early
Summer of 2021 the following work would take place.
Removal of intruding vegetation,
including Salix species, from woodland roadway/ stacking
area/turnaround and surrounding ditches. This work is to be
co-ordinated with Butterfly Conservation and volunteers (as previous)
to ensure maintenance of purple emperor population.
Subsequent conversations between Rob Parker, Julian Dowding
and Sam Felton resulted in a site meeting with a FE representative. An
agreement was reached by Sam, that, with volunteers’ help, he would
endeavour to rescue any vulnerable Purple Emperor (pupae).
On Tuesday 29th June Forest England worked in the wood, but
those who had assembled to rescue pupae were prevented by FE from
entering the site of operation owing to COVID-19 regulations.
Since then, an assessment of the effect of the work on
butterfly pupae is being made.
Naturally there is concern for
the manner in which future operations in the wood are handled by FE.
Borrow a Moth Trap
Are you intrigued by moths but haven’t delved into a moth
trap? Moth Traps are relatively expensive items and most people
only want to use one once or twice a year to find out what moths are
flying in their garden.
The Branch has purchased an MV Robinson moth trap and an
Actinic Skinner moth trap for the members of Suffolk
Branch to use during this summer
season. If you have limited experience, or
are a beginners in the moth world, you can borrow a trap for a period of
up to one month for use at your own location.

You can then help the survey of moths in Suffolk by entering the moth records into

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

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.
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.

The UK Butterfly Monitoring Scheme (UKBMS)
UKBMS report for 2019 is now available.

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

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.

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.
