Distribution Maps for Suffolk Butterflies
The Suffolk Butterfly Recorder, Bill Stone, has prepared
distribution maps for 2011 - 2015 for all the butterflies that can be
found in Suffolk. 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.

Wider Countryside Butterfly Survey
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.
We have eight squares
in need of a volunteer

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
