Numbers soar to 73,000 during three-week survey after mild winter and warm spring
The number of red admirals in Britain soared over the summer despite the soggy conditions, according to conservationists who said public sightings of the butterflies had risen to their highest since 2010.
Results from the Big Butterfly Count show that sightings of red admirals reached 73,000 over the three-week survey, a rise of 75% on 2016, and as many as were counted in the past three years put together.
