Rare butterfly spotted on New Addington chalkland reserve
Naturalists at Hutchinson’s Bank nature reserve are celebrating the sighting of a rare butterfly.
Naturalist Martin Wells captured this image of the rare brown hairstreak butterfly at Hutchinson’s Bank
Hutchinson’s Bank is one of the richest remaining chalk grassland habitats in London, and this year it has been just a touch richer with the appearance of the brown hairstreak butterfly.
London Wildlife Trust has been working to expand habitats for around 30 butterfly species at the nature reserve. The butterflies include grizzled skipper, dark green fritillary, small blue, brown argus and chalk hill blue. All have been helped to thrive by the Trust’s work to reduce scrub encroachment and allow controlled grazing, but it was the sighting of the brown hairstreak that really highlighted the project’s success.
