- Emperors Reign - Over the last couple of weeks, David Brown has been conducting a survey of Emperor Moth in our region by using a captive bred female as a lure to attract wild males.
On the 29 April as part of David's 'Winged Splendour' course, a visit to Oversley Wood resulted in a captive female attracting two wild males, an exciting record as the moth has not been recorded at Oversley for 53 years!
With perfect weather conditions and four obliging (calling) captive reared females, David visited several sites in Warwickshire where the habiat held some potential for the species to be present. Burton Dassett Hills drew a blank but the woodland ridge above Warmington village revealed a single male attracted by the pheromones emitted by the calling females. David then moved to the other end of this escarpment with his ladies to Edge Hill where he knew of an open sector of woodland containing Bramble by the roadside. Bingo !!!!....a male arrived after only 5 minutes suggesting that the Emperor reigns all along this ridge.
On the 3rd May, the females failed to bring in any male Emperors on the Lias grasslands at Bishops Hill, Harbury Spoilbank/adjacent railway cutting and Ufton Fields. However, on my return home to Charlecote at 2pm I left the cage of females hanging in my garden. At 4.30pm a male arrived to the cage. This is the first David has recorded here since 14th May 1974 when a male was also assembled to a female.
As David suggested in his book"The Larger Moths of Warwickshire" ...Emperor may survive at low density over a wider area of the County...
The last Oversley Wood record of this species back in 1960 was by D.W. Scott who found 4 larvae on Blackthorn. It is quite feasible that this species could have remained in Oversley Wood or around the edges of the woodland all these years undetected.
During the 1960's there was evidence that this moth existed in suitable habitat away from large tracts of heathland in Warwickshire. R. Evans found larvae on bramble at Claverdon railway cutting.
In the 1970's " ample sized" males were assembled to caged females at Hampton Wood and to a Charlecote garden.

- Ryton Wood - The final woodland management task has been completed. In total 24 coppice projects were completed. All 17 coppice cycles had at least 1 project completed.
- Sherboune Farm - To support the farm's Higher Level Stewardship, volunteers helped to plant a native shrub understorey in a plantation woodland. A butterfly scallop cut into the side of a plantation has provided an opportunity to plant native wild flowers to encourage woodland and grassland species.
- Ryton Wood Meadows - 450 blackthorn, 100 hawthorn and 75 alder buckthorn whips were planted to create new hedges to support Brown Hairstreak and Brimstone butterflies. 3000 dog violets were planted to create extra habitat for the Silver-washed Fritillary.
- Stockton Cutting - Following extensive clearance at Stockton Cutting the area has been seeded with birds-foot trefoil and kidney vetch to help the Small Blue, Dingy Skipper, Green Hairstreak and Common Blue butterflies.
- Oxhouse Farm - Meeting were held to discuss scrub removal from calcareous grassland and a disused rail line to help the Dark Green Fritillary, Grizzled Skipper and Dingy Skipper.
- Wood White - 4.5 kilo’s of meadow vetchling seeds were distributed in key locations in the Princethorpe Woodland area to help the survival this at risk species. Only a single wood white was recorded in the whole of Warwickshire in 2012.
- Hunters Lane Wildlife site, Rugby - Liaison has begun with SUSTRANS following the creation of a new cycle route on the route of a disused railway line. Bare areas have been seeded with birds-foot trefoil to create suitable conditions for colonisation by the Dingy Skipper and Green Hairstreak. Abundant creeping cinqufoil is already present a work party is planned to ensure this cinqufoil presents suitable egg laying opportunities for the Grizzled Skipper.
- Forestry Commission - Meeting with the friends of group has taken place. A plan is developing to create far more habitat for the the rare Argent and Sable moth and White Admiral butterfly. A new butterfly transect has been established on the this site. As part of this project a new transect has also been stabled at Weston and Waverley Wood.
- Talks - A talk has been given on the conservation of butterflies to the Rugby High School for Girls.
- Partnership meeting – One was held with the Princethorpe Woodlands working group.
- County Local Biodiversity Action Plan (LBAP) - Comments were made on the County LBAP plans for the Argent and Sable and Chalk Carpet moths.
- Stamford Hall - Following advice on their Higher Level Stewardship violets were planted at Stamford Hall.
- Malpass Quarry - Further advice was given on the mitigation plans for the climafuel plant.
- Draycote Water - Butterfly Conservation displays were at Draycote Water for there open day. Discussions were held on the ongoing management for the habitat created for Dingy Skipper and Grizzled Skipper.
- Woodbine Farm - Advice was given regarding possible habitat creation for the Dingy Skipper and Grizzled Skipper. Discussions were also held on how the farmers rare breed livestock could be used for conservation grazing to benefit butterflies and moths.
