Increasingly the segmentation between birders, butterfly watchers, dragonfly watchers and photographers is reducing as interests overlap and there is a demand for books that cover the three popular groups of birds, butterflies and dragonflies. Having written and photographed the guide to the birds of Sri Lanka in the series, Gehan de Silva Wijeyeratne has produced a single, compact and portable photographic guide to the butterflies and dragonflies of the country. The emphasis in the 280 species featured is on the commoner species, covering around 90 per cent of the species that a visitor is likely to see. It is also an excellent book for residents to learn about the commoner butterflies and dragonflies before progressing to more advanced technical books. The guide is focused on field use to help beginners and experts identify species and provides information on their distribution and habitats. As identification of butterflies and dragonflies require a different approach, the two sections are done as two mini photographic field guides with common introductory sections to wildlife watching in Sri Lanka. The book includes information on the key wildlife sites, general introductions to the biology of dragonflies and butterflies, up-to-date checklists with local status and useful references for people who wish to progress further with their study of these charismatic and photogenic animals.

In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults.
