Additionally, there is a record in the 1966 Proceedings of the Bristol Naturalists' Society of Adonis Blue Polyommatus bellargus. The record states 'Chew Valley Lake - few pairs' on 3rd September 1966. Given that there are no other records of this species at Chew, and that the foodplant (Horseshoe Vetch) has never been recorded here, this must call in to question the validity of a record stating that a few pairs were present.
