Mark,
They are unofficial introductions.
The Derbyshire Butterfly Net is a sub-domain of Derbyshire Dragonflies (
www.derbyshire-dragonflies.org.uk). The latest posting on the Butterfly News (29 Aug 06) is headed 'Carr Vale Large Coppers' - 27 August - Roy Frost reports:
Tony Irons 'phoned this afternoon with the news that he was watching 3 Large Coppers at Carr Vale NR. When I got there 30 mins later there were 4 and in a short stretch of 40m we found 9 more to make a total of 6m, 7f including a pair in cop. They were at the N end of the main lagoon, just beyond the seat and between the track and the water. All were pristine and this, plus their close proximity, suggests that they were liberated as adults rather than, say, as larvae on the adjacent Great Water Dock. This seems to be a new species for the phantom liberators of the Midlands. Others released locally include Wood and Marbled Whites, Niobe, Marsh and Heath Fritillaries, Large Tortoiseshell, White Admiral, Scotch Argus and Brown Hairstreak. (Roy Frost)
An additional footnote:
And after all these years we thought that there was only one Large Copper at Carr Vale NR. These butterflies, although no doubt captive bred, are stonkers and are giving a great deal of pleasure to many people. (RTT)
FJ Note: The 'locally released list' is of special interest when we consider recent introductions at Chambers Farm Wood, Bardney.
Regards,
