It was six years since I’d last seen a Chalkhill blue so it probably comes as no surprise that I took rather a lot of photographs of these gorgeous butterflies during my two visits to Tout and King Barrow Quarries on the Isle of Portland, in Dorset, last week.

I decided it would be easier to share the best of these in the form of a video slideshow, and I’ve also included a few photos of the quarries to provide context and give an indication of the habitat in which these butterflies thrive. Tout Quarry has the added benefit of being an open air sculpture park, so it’s very easy to spend many hours there, delighting in both the natural beauty of the butterflies and the creativity of the sculptors.
