Butterfly Conservation’s Bill Downey engaged the Friends of Juniper Hall with a feast of photos of these beautiful creatures of the summer – a welcome diversion on a damp November day. Evolving alongside flowering plants over the past 150 million years, their existence remains sensitive to changing conditions due to their short life cycles. They represent canaries in the mine and are closely monitored through 155 long-term survey transects orchestrated by Bill in Surrey alone. These contribute to the evidence of a worrying situation with 80% declines since the 1970s. Bill and teams of volunteers work hard to enhance habitats for butterflies, promoting the growth of the all-important food plants for their caterpillars, such as kidney vetch and horseshoe vetch on the North Downs.
Bill put our knowledge to the test with photos of six different species some had previously lumped together as ‘cabbage whites’ (large whites, small whites, green-veined whites, brimstones, orange tips and wood whites)! He limited the quiz on ‘blues’ to those found on chalk grasslands – still an impressive number of stunning little butterflies with exquisite and subtly different markings.
