 Dragonflies in Suffolk Newsletter

The first newsletter from the local Suffolk Dragonfly Group is available with information on recording and some up to date dragonfly and damselfly atlas maps and an interesting table showing the first and last occurence dates of the species.

 National Dragonfly Atlas Project - 2008 to 2013

The National Dragonfly Atlas Project will be launched in April 2008. The aim of this project is to update the known distribution of British dragonfly and damselfly species over the next 5 years, culminating in the publication of a new national atlas in 2013.

A new national atlas is urgently required. Climate change is contributing to increasingly earlier spring emergence and change in the range of a number of our species. In addition, new species are becoming established in Britain, as demonstrated by the recent rapid spread of Small Red-eyed Damselfly. We are living through a dynamic change in our dragonfly fauna and need to record this information, thereby providing evidence for future assessment of the impact climate change and other environmental factors are having on our dragonfly fauna.

Can you help with recording the dragonflies and damselflies in Suffolk?

Recording
The minimum effort required for the atlas would be to get at least a complete species list for a 10km square, based on several visits through the flying season. Three visits per site will be needed to cover all the possible species with one visit early season for Large Red Damselfly etc, one late season when resident Darters and Migrant Hawkers are on the wing and one mid-season to pick up the main species.
 
The maximum effort would be a detailed look at each individual water body in the10 km grid square. The key sites should be covered at the 1km level if possible. Although most surveys will probably fall towards the minimum effort end of the spectrum, a good general strategy would be to ensure that all key species (RDB species plus local scarcities) in a 10 km square are identified and recorded.
 
The visits should take place between 1100 and 1400 with the air temperature in the shade above 17ºC and cloud cover not exceeding 50%. Wind should not exceed force 4 on the Beaufort scale (leaves and branches moving).

 2011 update

Dragonfly Atlas Update 2011
 
Thanks to those you have submitted records for 2011 and a request for members to submit records for the season to help coverage of the distribution of the damselflies and dragonflies in Suffolk.
 
Next year will be the final year of the atlas and we would welcome recorders to send in all records along with helping to cover areas that are under-recorded. A coverage map will be added to show areas that need more visits to make a complete a picture of the county’s odonata as possible. Below is a map of Common Darter sightings from 2008-2010. Further maps will added i nthe new year including a coverage map.

Please send records to Adrian Parr, County Dragonfly Recorder, email: adrian.parr@btinternet.com


  
 2010 update

Dragonfly Atlas Update 2010

The 2011 season represents the penultimate year of fieldwork for the new national Dragonfly Atlas. Already a number of significant changes to Suffolk’s dragonflies have been uncovered – the highlight is no doubt the colonisation of SE Suffolk by the Willow Emerald Damselfly, but a number of more traditional species have clearly also been expanded their ranges in recent years. Scarce Emerald Damselfly now appears to be established in the county in the Market Weston/Redgrave area, while Hairy Dragonfly, Norfolk Hawker and Scarce Chaser in particular are also doing well. In the last few years, Scarce Chaser has for instance appeared on the River Gipping near Needham Market, on the upper River Lark and at Lakenheath Fen. Even Variable Damselfly, a species giving some cause for concern nationally, has recently turned up at Lakenheath. Not all news is however good, with Emerald Damselfly so far having been observed at only 40% of the number of sites as in the last census some 20 years ago. Hopefully some of this however represents a degree of under-recording, and there is still time for people to get out and discover new sites for a range of species. In particular, parts of both west and central Suffolk could still do with more intensive coverage. Records are however welcome from all areas, and for all species!!


  
 2009 update

Hi to all SOG members
 
Dragonflies and Damselflies in Suffolk 2009
 
 
I hope you are all enjoying the sunny weather. It's certainly been quite a good season for dragonflies this summer, which is good; long may things continue! If anyone feels like venturing a little further afield during the next few days sunshine, I've attached a map of Blue-tailed Damselfly records from 2008, showing which areas were well-recorded and which were poorly-recorded during last year's Atlas fieldwork. Tetrad and 1km x 1km square records are both shown; we hope to ultimately work to 1km x 1 km, or better, resolution. Hopefully we can get as many squares filled as possible this season.
 
2008 Blue-tailed Damselfly records
 
News from the county this year is good - Scarce Emerald Damselfly has just been confirmed from Redgrave Fen, and there's an unconfirmed report on the BDS hotnews website of Scarce Chaser near Needham Market . On a slightly wider scale Dainty Damselfly has just been recorded on the Channel Islands after a 60 year absence, and it would be nice if it one day returned to East Anglia.
 
Who knows what the coming weeks might bring?
 
All the best, and good hunting.
