Butterflies of Serra Dos Orgaos, 2020

Bizarro, J. and Martin, A., 2020. A Guide to the Butterflies of the Serra Dos Orgaos, South-eastern Brazil. REGUA publications. ISBN: 978-0-9568291-2-2  389pp  Review

As guide books go, this is not one for the pocket, but this is a magnificent tome (20x24cm) which depicts in perfect colour all the known butterflies of this part of SE Brazil. It is in English, but if it were in Portugese as well it would be twice as long.

The book includes a total of 923 species of butterfly recorded to date from the Serra Dos Orgaos in the State of Rio de Janeiro.  This includes the very difficult skippers (120 species) which have only been given general descriptions. That leaves 803 butterfly species are described completely with Scientific and Common names, descriptions, similar species, distribution and ecology. There are 58 species which are listed as Threatened in Brazil, and 14 of these which are found in the area, are included too. There is so much natural habitat in the REGUA lowlands to the ridge line of the Organ Mountains (2,260 m) to be explored that many more butterfly species will be discovered. Butterfly lovers wanting to discover new butterfly species need to head for the REGUA reserve.  Also included in the book are 5 butterfly species that are waiting to be described and named, one Symmachia sp. three satyrs and one Gorgythion skipper.

The authors include Dr Jorge Bizarro with a background in medical entomology and a passion for butterflies, and Alan Martin FLS, a renowned ornithologist and professional accountant who has fully embraced an enthusiasm for lepidoptera with a background in helping some of the leading UK and global conservation NGOs.  Other publications from REGUA include ‘A Guide to Hawkmoths of the Serra dos Orgaos’ in 2011 and ‘A Guide to Dragonflies and Damselflies of the Serra dos Orgaos’ in    and ‘A guide to Birds of the Serra dos Orgaos’ in 2015. So this is REGUA’s fourth publication, a credit to their professional output.

Extensive field work carried out by the authors and their many colleagues at the field station in REGUA has enabled this comprehensive compilation of butterflies of the area. It is in an area that Charles Darwin visited, and it still offers naturalists alike the opportunity to explore, discover and describe wildlife. The illustrations in the book, some 88 plates are key to identifying the species, all reproduced in superb colour, 15 species a page, almost all mostly shot in the wild. The range and diversity is stunning, but then the quality of the hinterland of REGUA is of perfect Atlantic Rainforest, a rare and declining habitat recognised as being in the top five global biodiversity hotspots in the world; there is only 16% of Atlantic rainforest left (it used to stretch south from the mouth of the Amazon), and REGUA with its 18,000 acres seeks to conserve (and enhance with native plantings – over 624,000 trees planted to date) what is left.  Bringing back the native flora is key to supporting and expanding the potential of butterflies and moths.  The new acres of wetlands increases the biodiversity of insects across many orders of insects including lepidoptera.

The guide will be immensely useful to visitors to these neotropical tropical habitats in Rio de Janeiro state and all those who wish to start identifying from their digital images.  As stated, the book is too large to have in a knapsack (it is over 1.1kg) but a copy needs to be in all field schools, field labs, libraries and university ecology and conservation departments, as a key reference book.

There is a Glossary, Latin Name Index, additional reading and references, and the list of Threatened species. This is a remarkable compilation and sets an important milestone in butterfly research in this wonderful part of the world.
