Cynthia Longfield

Cynthia Longfield (16 August 1896 – 27 June 1991) was an expert on the dragonfly and an explorer. She was called "Madame Dragonfly" for her extensive work. She had an analytical mind and was passionately fond of dragonflies. Her dominant area of interest was natural history. She travelled extensively and published The Dragonflies of the British Isles in 1937. She worked as a research associate at the Natural History Museum, London. Longfield was the expert on the dragonflies at the museum, researching particularly African species.
After retirement from the NHM she returned to Castle Mary, the family estate, in Cloyne, County Cork where she lived until her death. She died on 27 June 1991 and was buried in St. Coleman's Church of Ireland Cathedral, close to her home in Cloyne.
