Phil Sterling is a lifelong lepidopterist and is the senior author of the Field Guide to the Micro-moths of Great Britain and Ireland. Barry Henwood has devoted much of his entomological time over the past 40 years to rearing larvae of macro-moths, and to furthering an understanding of their life histories, and is one of just a handful of experts in Britain in this area. Richard Lewington is an acknowledged leader in the field of insect illustration. His meticulous paintings of wildlife are the mainstay of many of the modern classics of field-guide art, including The Butterflies of Britain and Ireland, Guide to Garden Wildlife and Field Guide to the Bees of Great Britain and Ireland. Richard has also designed and illustrated wildlife stamps for several countries. In 1999 he was awarded Butterfly Conservation's Marsh Award for the promotion of Lepidoptera conservation, and in 2010 the Zoological Society of London's Stamford Raffles Award for contribution to zoology.
