The Glanville Fritillary is virtually restricted to coastal landslips on the southern half of the Isle of Wight.  It was named after Lady Eleanor Glanville who was the first to capture British specimens in Lincolnshire during the 1690s.  The status of the butterfly appears to have changed little in recent decades, though there has been some loss of habitat due to coastal protection measures.  However, there are only a handful of core breeding areas and it remains a vulnerable species.
