Educated at Cambridge University and subsequently at Wye College where he studied economic entomology and then worked under Theobald on aphids and frog hoppers. When Theobald died Duffield became entomological adviser to the Cooper Technical Bureau. In 1935 he inherited sufficient funds to enable him to retire and purchase land around his house at Ashford, Kent. Some of this land was subsequently acquired by the Nature Conservancy Council and now forms part of the Wye and Crundale Down National Nature Reserve. Duffield's particular interest was in the conservation of rare insects and plants in his own area of Kent. He published three notes on Coleoptera in the EMM. 'A note on Liparius germanus L.' (57, 1921, pp.142-43); Anthonomus cinctus Kollar in Kent' (58, 1922, p.37); and 'Odontaeus armiger Scop. in Kent' (61, 1925, p.225). Duffield's collections were placed on loan in the Maidstone Museum after his death. FRES 1913-40, 1947-1974. BENHS member from 1949.
