Donald L.J. Quicke retired in 2013 to live in Thailand where he is a Visiting Professor at Chulalongkorn University. Hestudied zoology at Oxford University where he became especially interested in mimicry. In 1976 he travelled to Kenya to experience tropical biodiversity and more of the diversity of life and his work there on insect coloration fertilised his interests as well as on parasitoid wasps, another of his many passions. From then on he kept abreast of the increasingly experimental and theoretical developments in the field even though his academic research took him in diverse other directions. Having now retired he has been able devote his time, in addition to bird watching and butterfly photography, to synthesising and extending his interest in this topic. Mimicry, Crypsis, Masquerade and other Adaptive Resemblances is the result of this work.
