Covering the 43 resident species that occur in North-west England (out of 49 in the UK), this 120-page book summarises the key features to look out for on this difficult but fascinating group of Geometrid moths. The information on finding pugs make this a useful introduction to moth recorders outside of this area as well. Each species account gives a short morphological description, mentions what is known about larval food plants, and describes distribution and flight period. For each species photos of the adult moth and, where available, the larva, a colour distribution map, and a chart showing the flight period are included.
"[...] s an excellent little book, which makes a real contribution to the studv of pug moths – a rather neglected but delightful group of moths. [...] excellent value for its price and will surely become a valued part of any lepidopterist's library"
– Mark Young, Atropos 61, 2018
"This extremely helpful publication is the result of many years of work by Brian Hancock, a pug enthusiast from north Lancashire [...] I think that those readers living outside the north-west of England, but keen to learn more about this group of moths, will find much in this reasonably priced volume to confirm the wisdom of their purchase, as the potentially daunting task of pug identification is helpfully explained by the author."
