In Europe the Glanville Fritillary is found in a wide range of habitats including woodland glades, sub-alpine meadows, field edges, and open grassland.
In Britain it is at the edge of it's range and is only able to survive at a handful of particularly warm sites along the south coast of the Isle of Wight. The critical factor is probably the amount of sunlight which sites receive in late winter and early spring when the caterpillars awaken from hibernation - the Isle of Wight receives more hours per day of sunlight at this time of year than elsewhere.
The butterfly breeds primarily on severely eroded sandstone undercliffs, where the larval foodplant ribwort plantain grows in profusion, and where the extensive areas of exposed ground create a very warm micro-climate. Most sites only support colonies for a few years because they soon become overgrown, lowering the micro-climate until it eventually becomes too cool for the species. Luckily regular land slippages create new areas of habitat which the butterfly can colonise, and the status of the butterfly on Wight remains fairly stable. Sea defence constructions and tourist developments do nevertheless threaten to destroy several of the butterfly's breeding sites.
Away from the coast the butterfly also breeds periodically on the chalk grassland hillsides on the southern half of the island, but these colonies tend to last only a year or two.
Occasionally temporary colonies become established on mainland Britain, e.g. at Hordle Cliffs and Hurst Castle. They typically flourish for 2 or 3 years, but then disappear. They are almost certainly the progeny of single females which periodically find their way across the Solent, so the genetic diversity of each colony is minimal. After a few generations genetic entropy weakens the stock, reducing the viability of the colony, and rendering it prone to extinction

A wonderful shot of this beautiful Glanville Fritillary. The markings of most fritillaries are always quite intricate and this one is no exception. Your opened wing presentation shows it off in fine fashion. Beautiful colors and tac sharp focus. Great work!!
