Given the latest government advice
to avoid social gatherings and venues, Suffolk Butterfly Conservation
and the Suffolk Moth Group have regretfully made the decision that it
will be in the best interests of everyone to postpone or cancel our
later in the year when it is hoped this disease will be under control.
We are sure you will agree we have a duty of care to those wishing to
attend and given the present situation, we believe this is the correct
decision in these difficult times to ensure the welfare of everyone
The events page will be revised when we
are in a position to run events on new dates where possible.
All events for 2020 are listed on our events page
The programme of events for Suffolk Moth Group has
been published on the Suffolk Moths Blog

Wider Countryside Butterfly Survey
The UKBMS has taken government
advice on board and decided that all transect walking and WCBS
recording should cease, until such time as these restrictions can be
safely lifted. Butterfly recording is not an essential activity and we
cannot justify promoting it in the current circumstances
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.
We have 11 squares
in need of a volunteer. For details

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
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.)
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
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
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.

website for Suffolk Moths
Conservation is for moths as well as butterflies. There is now a

with photographs, distribution maps and latest sighting dates.

End June Update- Suffolk Butterfly
Recording 2019- "Black-Holes"
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.
see the maps click here
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.
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).

UK Butterfly Monitoring Scheme
Some interesting information here. The 10 year trend shows a
31% decline in the Purple Emperor despite an increase in Suffolk.
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
The Branch is always grateful for butterfly records and a
recording form can be downloaded from the recording
page of this
We would be particularly grateful for records away from the
coast and information on the following species:
Green Hairstreak, Purple Hairstreak, White Letter Hairstreak,
Silver-studded Blue, Wall Brown, White Admiral, Silver-washed Fritillary, Grayling and Small
