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 was passionately fond of dragonflies and 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.

Cynthia Evelyn Longfield was born on August 16, on Pont Street, Belgravia, London. She was the youngest of daughter of Montifort and Alice Longfield, of Castle Mary, Cloyne, Co. Cork. She had two sisters. Alice Longfield grew up near to Oxford, and was the daughter of a scientist. Alice died in 1945. The family home at Castle Mary was burned down in 1920 by rebels, and Park House was rebuilt on the grounds.

She joined the Army Service Corps during WWI, later moving to an aircraft factory on Fullham Road. She visited South America between December 1921 and March 1922. She traveled to the Andes and Lake Titicaca. In 1923 she traveled to Egypt, where she caught a scorpion at the tomb of Ramases IX. In the same year answered an advertisement to join Evelyn Cheesman of London Zoo on a research trip to the Pacific, specifically the Galapagos Islands. They sailed aboard the St George, which left Dartmouth on April 9, 1924. She collected coleoptera and lepidoptera as an assistant to an entomologist, Cyril Collenette. The pair used machetes to hack through the undergrowth of the Amazon jungle in order to collect specimens for the Natural History Museum of London. She joined the Entomological Society of London in 1925, and later the same year joined the Royal Geographical Society. She was the first woman member of the Entomological Society. In 1926 she joined the London Natural History Society. She was elected president of the society for 1932 and 1933. On March 28, 1938 she joined the Auxiliary Fire Service, and ensured that a turntable ladder was used upon the bombing of the department in April 1941, during WWII. Cyril Collenette stated that her actions in relation to this likely saved the Museum from destruction.

Longfield was a voluntary cataloguer at the Natural History Museum and was put in charge of work on dragonflies. She joined a six month expedition to Matto Grosso, Brazil in 1927, and returned with samples of 38 of species of dragonfly. Three of these species were previously unidentified. The species Corphaeschna longfieldae is named in her honour. By 1937, Longfield had become an international authority on the subject of dragonflies and published a book entitled "The Dragonflies of the British Isles". The book quickly sold out, and earned her the name "Madame Dragonfly". She was appointed an honorary associated of the Natural History Museum in 1948.
