Table of Earliest Dates Recorded

The table now has entries for all the county species. The late emergence of species compared to last year is now less evident than seemed the case earlier in the year though the position is mixed. Beautiful Demoiselle, Black-tailed Skimmer and Emperor Dragonfly were recorded a few days in advance of the previous earliest date. However, Southern Hawker, Brown Hawker and Emerald Damselfly were a month or more later than their earliest recorded emergence in Warwickshire. The Emerald Damselfly, was exceptionally early last year, 2007. The relatively late emerging Small Red-eyed Damselfly was sighted a week earlier this year.

Probably the mild winter of 2006/7 and exceptionally mild early spring (see Met Office 2007) allowed the larvae to start feeding early and progress rapidly to emergence in 2007. The 2007/8 winter and early spring were also mild but not exceptionally so (see Met Office 2008). The poor weather last summer and this spring may have delayed emergence and reduced numbers of some species this year. In particular the Red-eyed Damselfly, appears to be present in small numbers this year relative to other years.

The 2008 earliest dates are highlighted in red.

News for 2008 until 14 August

A most unusual dragonfly sighting was reported by Peter Davies in his garden at Dunchurch on 19th July, Golden-ringed Dragonfly. Though Peter is not an experienced dragonfly watcher, my initial scepticism of his report was dispersed by the description he sent and gave me in a subsequent discussion. It is very, very probable he did see Golden-ringed Dragonfly which is a very rare vagrant in Warwickshire. The nearest breeding population is probably that at Catherton Common in Shropshire - unless there is an as yet unrecorded populations near Dunchurch! It is thanks to Peter's careful observation and report that we have this rare record.

All known breeding Warwickshire dragonflies are now flying in the county, see earliest dates above. The numbers of individuals of some species seems to be lower than has been typical in the past few year. As note above, Red-eyed Damselflies appear significantly down in numbers this year. This does not appear to be the case with the Small Red-eyed Damselfly, now at the height of its flying season, which visits to Marsh Lane Reserve, Hampton-in-Arden and Swift Valley Reserve, Rugby confirmed. Carefully check any Red-eyes you see to determine if they are Large or Small, see the Red-eyed Damselfly identification page. Try to visit any ponds you know with good submerged and surface vegetation to look for this species and help monitor its spread through the county.

The distribution maps for all species have been updated with all records I have received to date.

News for 2008 until 18 June
Beautiful Demoiselle

Beautiful Demoiselle photographed by Phill Clayton ©, 11 May 2008
This is the first news report for 2008, somewhat later than usual. The cause of the delay was Kay and my four week French dragonfly holiday. And very successful it was too! We were targeting a new species for us, the Two-spotted Dragonfly Epitheca bimaculata. In addition to finding this species we totalled up 30 species during the break and had some excellent French food! Back to Warwickshire.

As the earliest dates tables shows things have got off to a slow start, particularly compared to last year's early emergences. However, Phill Clayton spotted and photographed Beautiful Demoiselle on or before 11 May.

The distribution maps in the Atlas are updated with all they 2008 records received by 18 June 2008

RSPB Reserve, Middleton Lakes, Warwickshire/Staffordshire border - 13 July 2008

This field day was at the RSPB's new reserve which is yet officially open to the public. The reserve is 160 hectares of exhausted gravel quarrying. There are a number of water bodies of varying size on the site, mostly still at an early successional stage. The RSPB is still working on profiling some pools. Very little dragonfly recording has been done on the site and we were hoping to start the process.

A very good turn out of more than thirty gathered at the car park. Most were from the Warwickshire Group but about half-a-dozen were from out of county. Lesley Barton-Allan, Biodiversity Officer for the site, was our guide. We set out in warm conditions under grey skies to tour as much of the area as possible. We were occasionally blessed with a sunny period and we started to find and record dragonflies. We visited pools and the river Tame which bounds one side of the reserve and gradually worked to the north of the site. After lunch we reached the pools in the north which are still very raw with little vegetation. But Black-tailed Skimmers were already there exploiting them.

On our return route we found a delightful small pool, at a much later successional stage than most on the site, with emerging Common Darter. A number of exuvia were recovered. In total we found ten species, none in great numbers. They were: Azure Damselfly, Banded Demoiselle, Black-tailed Skimmer, Blue-tailed Damselfly, Broad-bodied Chaser, Brown Hawker, Common Blue Damselfly, Common Darter, Emperor Dragonfly and Southern Hawker.

It was an interesting visit to a site at an early stage of development with great potential to be first rate for dragonflies. Thank you to the RSPB for allowing the access and to Lesley for her help in organising the trip and on the day.

Adult Identification Workshop, Brandon Marsh - 5 July 2008

There were nine participants in the Adult Identification Workshop.

As usual, the day started with a slide show illustrating the features needed to discriminate between the various species likely to be seen in Warwickshire and further afield. The group then went out into the Reserve to exercise their newly acquired skills. The weather was not the best for dragonflies but by dint of effort seven species were found and identified but no species was about in other than small numbers.

Thank you to the Warwickshire Wildlife Trust for providing the facilities.

River Avon, Eckington Bridge, Worcestershire - 28 June 2008

What a difference a day makes albeit after an interval of a couple of years. The object of our visit to the site, as it was on our unsuccessful visit 2005, was to find the Scarce Chaser. The weather on this visit was bright, warm and breezy and compared with 2005 was much more productive.

Sixteen of us assembled in the car park and even before the official proceedings began a small group was seen huddled in the corner of the car park observing and photographing the first Scarce Chaser of the day. A good start!

Group at EckingtonBefore lunch we set off downstream and it quickly became evident that Scarce Chaser was present in good numbers. Mature males were stationed every few metres along the bank. There was plenty of male/male interaction and a few matings were observed. The other expected riverine species, White-legged Damselfly and Banded Demoiselle, were also present in good numbers and showing breeding behaviour. It was very enjoyable observing and photographing them all as the picture of some of the group shows.

The count of species mounted. Large Red, Red-eyed, Azure and Blue-tailed Damselflies and Emperor Dragonfly and Black-tailed Skimmer were all present in greater or lesser numbers.

We returned to the car park for lunch and to Mike Averill suggesting that Club-tailed Dragonfly was a prospect for the afternoon.

After lunch we tried the opposite bank upstream. The Scarce Chaser and the other species were there in similar numbers to the morning excursion. However, much searching fail to yield a Club-tailed and some gave up and returned to their cars. Those who did not in the end got their due reward. A lovely male Club-tailed Dragonfly which, very cooperatively, sat perched on the bank-side vegetation for several minutes allowing observation and photography.

There was satisfaction with a good day dragonflying as we returned to our cars.

Larvae Identification Workshop, Brandon Marsh - 5 April 2008

As was the case last year, this ID workshop was very popular and oversubscribed. Some prospective attendees were disappointed. All being well, it will run again next year.

As usual, the day comprised an indoor and an outdoor session. The indoor session started with a short presentation followed by two hours "hands on" learning identification skills with dragonfly exuvia (larval cases). After lunch we went out onto the reserve to try our luck with pond dipping, with some success. Again, as usual, larvae of Large Red Damselfly, Red-eyed Damselfly, Four-spotted and Broad-bodied Chasers and Southern Hawker were found and identified.

The day was considered a success by all who attended. Thank you to the Warwickshire Wildlife Trust for providing the facilities.
