Following service in the army during the war, Heath was employed by the Biological Research Department of Pest Control, near
Cambridge from 1947 – 1952. In 1953 Heath joined the
Nature Conservancy and was based at the
Merlewood Research Station in
Cumbria (at that time part of
Lancashire). In 1967 Heath moved to Monkswood Experimental Research Station where he worked until his retirement in 1982 where he was head of the
Biological Records Centre. Heath described the now eponymous portable trap in 1965. A founder member and vice-president of the
Society of European Lepidopterology, Heath was particularly interested in the
Micropterigidae and bequeathed his specimen collection to the
Natural History Museum, London. John Heath was chief editor of the
Moths and Butterflies of Great Britain and Ireland series, published by
Harley Books. ==References==
