Welcome to the Suffolk Branch of Butterfly Conservation
Butterfly Conservation is a registered charity dedicated to the conservation of butterflies and moths

Areas With Few Records

Also known as 'Black Holes'.  The map and details have been moved from the Recording page to the 'Black Hole Map' page.  The old information up to 2013 can be accessed from there if needed.

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.

Treasurer and Membership Secretary Required For Suffolk Branch BC

Dom Hill has been our Treasurer for the last three years and reluctantly has decided that owing to increasing work commitments he will have to stand down at the AGM.  We are seeking a new Treasurer and, ideally, would start at the 1st Apr.  A period of shadowing with the current Treasurer can then take place until a formal handover at the AGM in October.  Many of the functional aspects of the accounts iare dealt with by Butterfly Conservation HQ so the Treasurer’s role is be a relatively simple one.  You do not need to be an accountant or book-keeper and no experience is necessary, though enthusiasm and an understanding of figures would be an advantage.

If you feel that you might be able to help the Branch in this important role please contact Dominic Hill - email  phone 07712 133197

Membership Secretary
We also have a vacancy for the position of Membership Secretary.  Sue Sidle has most ably held this post for the last 9 years and we thank her very much for her hard work.  She has offered to help anyone who comes forward to take on the role.  The key tasks are keeping an up do date list of the membership (the details of which are forwarded to the Membership Secretary each month by Head Office) and sending a welcome pack and information to new members. Anyone who is interested in taking on this role please contact the Chair Peter Maddison.

Note that the Suffolk Branch of Butterfly Conservation is entirely run by volunteers.  This means that the money we receive for membership subscriptions can all be used to help in conservation in Suffolk e.g. the work on Purdis Heath to increase the numbers of Silver-studded Blue.  If you enjoy the sight of butterflies each summer then a few hours of your time fulfilling one of the above roles will help to ensure their survival.

Wider Countryside Butterfly Survey (WCBS)

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 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. 

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.

We would be particularly grateful for records away from the coast and information on the following species:

Dingy Skipper, Green Hairstreak, Purple Hairstreak, White Letter Hairstreak, Silver-studded Blue, Wall Brown, White Admiral, Silver-washed Fritillary, Grayling and Small Heath.
