Single, portable volume compressing d'Abrera's world-renowned Butterflies of the World (see nhbs.com for volume listing). It is arranged to follow the systematics of the larger volumes, whilst making corrections and additions, whilst also covering several new genera, new species and a long-awaited review of the Neotropical genus Thecla (Lycaenidae).The colour illustrations have been reduced in size and the accompanying text is brief and written in a concise style. It must be emphasised that this volume does not replace the larger volumes, but is a most necessary supplement to them.
