Andrew Wood is the Hertfordshire butterfly recorder and also the records collator for the Herts and Middlesex branch of Butterfly Conservation. His interest in Lepidoptera has been lifelong, but it was early retirement in 2011 from a career in information management and technology that enabled him to devote more time to butterflies and moths.

His meticulous work over several years resulted in the publication by HNHS in November 2016 of his highly-acclaimed book, Butterflies of Hertfordshire and Middlesex. The book is the first comprehensive guide to butterflies in the two counties for almost 30 years. In addition to describing and mapping changes in the their range and distribution, it places different species in the context of their ecology. It also includes a very useful section on the best places to see them, including rarer species.

Andrew's 1875 Award was presented to him at the Society's 2017 Autumn Meeting by HNHS Chair Agneta Burton.
