Maxillaria picta orchid

Helmut Seehawer is visiting us at REGUA and continues to explore for orchids here.

Once again we walked with Helmut to the lofty Lagoinha summits, an extremely important area for orchid dispersal, full of Platyrhipsa brasiliensisStelis ruprechtianaOctomeria grassilabiaOncidium lietzeiPabstiela spZygopetalum pedicillatum, and so many micro orchids.

We came across these relatively common Maxillaria picta, first described by Sir William Jackson Hooker, English botanist in 1811. Hooker didn’t travel personally to Brazil but probably received these plants and then described them from collected samples.

Helmut is 84 years old and he was delighted to be scrambling up these rocky summits in search of his precious orchids.

We think the world of Helmut, his incredible dedication and knowledge that allows us to draw people’s attention to them and their importance in this very biodiverse region of the globe, after all, the Serra do Órgãos is known for over 1,000 species, or 5% of the world’s entire diversity of orchids!!

Treks and Walks at REGUA

If you are interested in treks and walks in the forest, we are definitely the right place to come to. REGUA has over 45 kilometres of well-marked trails with breath-taking views and stunning scenery.

It’s a good chance to get to know the Brazilian Atlantic Rainforest and its superb attributes. This wonderful area is quite rightly considered one of the most biodiverse regions of the world. Our local team of are well experienced and have walked these trails many times, over the years. Yet every time we find something new. 

The trail pictured is the Cachoeiras de Macacu to Guapiaçu trail, a walk of 14 km, and it will take you minimum of 4 hours. There are waterfalls and fresh cool water spots and even places to swim on a hot day. 

Above all, trails of this kind offer walkers a chance to see the importance of what REGUA is trying to do, restoring and protecting the forests to allow their ecosystem to function healthily. Isn’t this our responsibility?

Leon Restaurant winners


The first Leon restaurant opened in London in 2004 and soon won various awards for quality.

The success in the fast food service led to cookbooks, products and a meteoric expansion around the globe.

Attached to the name are firm convictions in innovation and sustainability. Puro Coffee, a brand of coffee, likewise believes in tropical forest conservation, having helped REGUA acquire an important parcel of forest. Puro supplies coffee to Leon and the chain ran a raffle for their staff early this year with a prize being a three day stay at REGUA and Rio de Janeiro.

The three lucky winners  Habiba Boulakila, Elie Holder, Alessio Giangrande, together with regional manager, John Brooks arrived yesterday at REGUA and spotted capybaras and caimans on their first walk.

We visited Miguel Hertal’s Arabic coffee plantation in Bom Jardim and the group will finish off their tour on Ipanema beach in Rio. They will be able to relate their experience to their customers and staff.  A great break for these lovely people!!

Jorge finds a Praying Mantis

Jorge appeared the other morning asking me to photograph an interesting Praying Mantis which he hadn’t seen before. “We have to get this to the Mantis team”, he said.

So I sent photographs and a description off to Leonardo Lanna of the research team researching Praying Mantis at REGUA.

Biologist Leo Lanna of the Mantis team said  “This is a male of Eumusonia genus, a grass mantis. We’ve registered them on our visits – what is cool is that REGUA is the only place where we see a great variation in the males colours. They are described as brown, but we’ve seen yellow and green ones, and this is the first one we have seen that is brown with green legs.

They live among grasses and tiny bushes, as well as leaf litter, mainly on more open areas, like fields and trail borders. You can easily identify them by the triangle segment on the tip of their abdomen. Males and females share this triangle-shaped segment though females have no wings. We discovered a healthy population in the garden of Casa da Pesquisa (REGUA’s research house) when we were there in 2017 and now in March we’ve found many more, from small ones to adult males and females. We didn’t find in any other area of the reserve, though, but this will definitely add to our work..”

It is so gratifying to receive news back from Leonardo, and exciting that REGUA is the first place where they have seen this colour variation. Leonardo is so enthusiastic, interested and generous with his time in providing valuable feedback. This encourages us to keep our eyes alert in the hope of finding another species.. 

Carea Castalia at REGUA

I recently came across this beautiful iridescent green butterfly several kilometres from the Reserve.

Jorge Bizarro, REGUA’s resident lepidopterist and head of research, confirmed the example as a male Carea castalia, also known as Castalia Green Mantle. Jorge had previously seen the same species on REGUA’s brown trail two years ago.

Adrian Hoskins, on his “learn about butterflies” website (Amazonia section) describes the family Carea as being some of the most beautiful butterflies on the planet and indeed coming across this individual, I could not believe the iridescent green on the thorax and wings.

These butterflies are stated to be restless and once take off difficult to follow in surrounding undergrowth which perfectly confirms Jorge’s experience of the butterfly he saw at REGUA.

As Jorge and Alan Martin are writing the book on Butterflies found at REGUA and the Serra dos Órgãos region, this photograph could well be included.

Should you have photos of butterflies seen here at the Reserve, please feel free to email them to us at aregua@terra.com.br as we would love to see them.

Duke University students visit REGUA

You will have recently read that the US charity SavingSpecies helped REGUA acquire a parcel of land. Once planted with trees this will be an important corridor linking two established forests.

We recently received students from Duke University in USA. The three students; Bridgette Keane, Chiara Klein and Jacob Levine set up camera traps in both remnant forest blocks to record the fauna present. In time, and once the replanting programme has been completed in the new plot, there will be comparisons with what is using the “new” corridor.

They also planned to take panorama images with the famous ‘Gigapan’ system, a system developed for taking many high resolution photos and stitching them together to make a massive panorama photo. 

Having set up their project, these delightful students left us to go onto the Golden Lion Tamarin project. After three days REGUA’s bird guide, Adilei and I collected the video material to see what was moving in these patches of forest.

The results were startling for we recorded a Cracid; Rusty-margined Guan (Penelope superciliaris), the less common Grey-fronted Dove (Leptotila rufaxilla) and White-tipped Dove (Leptotila verreauxi). The mammals were brilliant with a tail(!) of Brazilian Squirrel (Sciurus aestuans), several Agoutis (Dasyprocta leporina),  and Common Opossum (Didelphis marsupialis). To top it all Crab-eating Raccoon (Procyon cancrivorus) was also captured on film. These species are using the forest to forage, which is great for seed dispersal and helps the nutrient cycle. 

Most Neotropical mammals are nocturnal, and the use of camera traps helps us understand which animals are present in these forests.   We are really impressed that these species appear to be quite common in this fragment border and this is the required base line information for us to monitor the forest corridor once it is planted.

Giant Owl-Butterfly

Michael Patrikeev, recently sent us this photograph, taken at REGUA.

Jorge Bizzaro, REGUA’s Research Co-ordinator and very knowledgeable lepidopterist explains its taxonomy:

Idomeneus Giant Owl-Butterfly (Caligo idomeneus) in Guapiaçu Ecological Reserve, Rio de Janeiro, Brazil

“This individual from REGUA is a rarity… because it only flies during sunrise when most lepidopterists are … sleeping! Caligo idomeneus… the main characteristic is the very straight and defined median white band of the forewing present on both sides.”
For more information from Michael’s website see here :http://www.wildnatureimages.org/Insects/Lepidoptera/Butterflies/Nymphalidae/Morphinae/Caligo%20idomeneus.html

Great Horned Owls Part 2

You will all remember that our Great Horned Owls Bubo virginianus were first spotted near to REGUA in August last year by Fito Downs and Adilei, REGUA’s Bird Guide. Many visitors were delighted to see this enigmatic species and Adilei caught some images of their coupling at the time.

Adilei and I visited the same tree in late December to take a photograph of the resulting juvenile bird.   As you can see the juvenile has grown considerably and as it starts its first moult, the downy first feathers are being replaced by the first adult plumage.

Naturally we are delighted with the progress and hope that the juvenile decides to stay nearby like our Tropical Screech-Owls, we certainly have plenty of old suitable trees in the area. 

FioCruz researchers at REGUA

The Oswaldo Cruz Institute for Tropical Diseases (often referred to as FioCruz) is of global renown, considered one of the world’s leading public health research institutions. The Institute has been leading research and saving lives for many decades.

Recently, we received three researchers very interested in hanging insect traps designed to capture mosquitoes. Maycom Neves, Tiago and Agostingho Perreira are researching two species that are not known in their larvae stage. Interestingly enough one species, Wyeomyia knabi, first collected by Teobald in Cachoeiras de Macacu and sent to UK in 1901 was named after his beloved Wye College where he had studied.

Our researchers are looking for the young or their stages as larvae.  Sabethes forattteniiis another species that has been collected at REGUA but not very well known. Neither are a transmitter of diseases, but the FioCruz is always concerned with public health and lead research efforts into the lives of our friendly mosquitoes amongst many other creatures.     

After this brief introduction, I will certainly look out for these amazing creatures.   

New Lizard for REGUA!

REGUA’s Keeper of the Wild ranger Rildo da Rosa Oliveira funded by the World Land Trust found this banded lizard on the red trail at around 600 metres above sea level. This lizard has very short legs and if were not for the scales on its body, one could mistake it for a salamander, but salamander are not currently known to be further south than Roraima, Northern Brazil.

We had help to identify this individual from Canada’s naturalist Mike Patrikeev who stated it was Banded Galliwasp, Diploglossus fasciatus of the Anguidae family.

Indeed this example measured close to 30 centimetres in length, and Rildo said that in all his years as a ranger, he had only once seen this species before.

There is a similar Banded Galliwasp (Diploglossus lessonae) endemic to Brazil’s Northeast region, rated “Least Concern” by the IUCN, but I wonder whether it’s Atlantic Rainforest cousin is as common? In fact, we all wonder when we shall see another one.
