Work on the next REGUA field guide, Observation Guide to the Butterflies of the Serra dos Órgãos, is progressing at good pace, and with it lots of new knowledge about the local butterfly fauna, together with some novelties, new records from guests, volunteers and visitor’s photographs have been consistently pouring in.
One notable rarity was found by Duncan McGeough, a volunteer from Germany in October 2013, just 30 metres from the REGUA office. Ortilia polinella (A. Hall, 1928), a crescent butterfly, is a cousin of the Glanville FritillaryMelitaea cinxia from Europe. Known from less than a half-dozen localities in the Brazilian states of Minas Gerais, Rio de Janeiro and Espírito Santo, and also very seldom found in collections (only three females and six males in the Natural History Museum, London) this was a superb find!
Adults are mainly forest species that dwell in sunlit areas like trails, clearings, forest edges, etc. It’s biology is unknown, but other species in the genus use Justiciaspp. as foodplants (Acanthaceae). The photo depicts a worn female sun basking, probably in between short exploratory flights to find a suitable plant for ovipositing.
Duncan has also helped with the creation of the REGUA moth leaflet that guests can pick up at the lodge, featuring 60 common moths easily spotted in the moth wall.

One of REGUA’s objectives is to encourage a wider interest and knowledge of the incredible biodiversity of the Serra dos Orgaos. REGUA has already published three books covering Hawkmoths (2011), Dragonflies and Damselflies (2015) and Birds (2015).
Now Jorge Bizarro and Alan Martin are working on a 4th book covering the Butterflies of the Serra dos Órgãos. This is a mammoth task and will cover about 500 species, of which we have so far written the text for Papilionidae (28 species), Pieridae (36 species) and are now working on Riodinidae.
Each species text will include a description, notes on similar species, distribution and ecology plus of course photographs where available. An example is shown below.
We are still missing good photographs of many of the species that will be covered in the book, so we would welcome any photographs of butterflies taken at or near REGUA which should be sent to Alan Martin at email@example.com. It may take another year to complete the texts, so there is still plenty of opportunity to take those pictures, and of course every picture will be acknowledged if used.
In the recently published field guide on the odonata of REGUA, A Guide to the Dragonflies and Damselflies of the Serra dos Orgaos, the scientific name of the Blue-wedged Dancer is given as Argia claussenii. Rosser Garrison pointed out that this in fact is A. croceipennis, therefore we have amended our odonata list. We are indebted to Rosser for sharing drawings and scans of both species with us that support his view.
The appendages of these two species are quite similar and there are also considerable similarities in colour pattern. However, under the microscope the difference in the shape of the cerci (placement of ventral tooth) can be clearly seen.
In the field there are luckily also a few differences that help identify the species. Argia claussenii has clear wings, whereas those of A. croceipennis are amber colored, and A. claussenii has an occipital bar, whereas A. croceipennis does not. These characteristics are very much in line with the species occurring in fast flowing and rocky streams in the foothills of REGUA. Below are examples of both species, kindly made available by Rosser.

We are thrilled to be able to announce the imminent publication of our new REGUA publications field guide on the Dragonflies and Damselflies of the Serra dos Orgaos.
The book has been written by Tom Kompier and describes all of the 204 known species from REGUA and its surroundings. Illustrated with 560 photos and an additional 125 plates, we think this is a milestone in the study and observation of this stunning group of insects.
Publication is due in April. For pre-orders or additional information, please contact Tom Kompier directly at email@example.com.
