§ Dr. David Clarkasked the Secretary of State for the Environment if he will list those species of butterflies found in the United Kingdom which the Nature Conservancy Council regards as having significantly or substantially declined or as threatened or endangered.
§ Mr. WaldegraveI am advised by the Nature Conservancy Council that out of a total British list of 55 resident breeding species, one—the large blue—became extinct in 1979, 10 more are regarded as vulnerable or endangered, and 13 have declined in numbers and become less widespread since 1960 because of contraction of their habitats. The species affected are as follows:
308W
Butterfly species State of species Adonis Blue vulnerable Brown Hairstreak declining Chalkhill Blue declining Chequered Skipper declining Dark Green Fritillary declining Dingy Skipper declining Duke of Burgundy vulnerable Grayling declining
Butterfly species State of species Grizzled Skipper declining Heath Fritillary vulnerable High Brown Fritillary vulnerable Large Blue extinct Large Tortoiseshell endangered Marbled White declining Marsh Fritillary vulnerable Pearl-bordered Fritillary declining Purple Emperor declining Silver-spotted Skipper vulnerable Silver-studded Blue vulnerable Silver-washed Fritillary declining Small Blue declining Small Pearl-bordered declining White-letter Hairstreak vulnerable Wood White vulnerable
