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.

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. 

Brazilian Gold frog

Measuring less than one cm in length, the Brazilian Gold frog also known as “Saddleback toad” or “Brachycephalus sp.” are some of the smallest frogs endemic to South East Brazil’s Atlantic rainforest. 

They are found at very high altitude, where they are adapted to low temperature and high humidity. As a result, the populations are isolated and form technically “sky” islands on mountain tops. Over 16 species have been described.   As one can see from the photo, these amphibians have three toes on each foot, and two fingers on each hand, in contrast to the usual five digits of most frogs.

Whilst climbing in search of orchids in the recently purchased Lagoinha area with Helmut Seehawer last December, we came across a large number of these golden frogs in leaf litter.   On taking a photograph, one gave an enormous silent roar in protest and then leapt away a massive distance by our standards to safety. We left them to their lives in this isolated world.

Our thanks to Rainforest Trust who provided funding to purchase this land. It is located at around 1000m above sea level and nestles next to Lagoinha farm.

IUCN states that species here at REGUA are of “least concern” and very well protected from deforestation, but we hope that climate change and pollution won’t affect them adversely.


World Land Trust Ambassador Visits REGUA

We are always so pleased to share our work with interested parties and Patrick Sherriff’s lightening visit was no different.  

Patrick lives in Hong Kong, and is World Land Trust (WLT) ambassador to the Far East. Due to start a tour of the Andean countries, he took time to visit REGUA to see the hard work we are engaged in.

Patrick arrived on a boiling hot day and we started his visit at the Matumbo Gap, a series of properties acquired over several years with WLT support. The area Patrick is standing on is being funded by Petrobras (the well known Brazilian petroleum company). The first hillside behind him is the area funded by WLT and the reforested area behind Patricks hat was funded by Brazilian SOS Mata Atlantica.

A real funding fruit salad and an excellent example of people and organisations coming together in partnership to achieve great success. This co-operation has enabled us to protect and begin the restoration of this vital landscape. The forest corridor being created across the “Matumbo Gap” of land which is starting to connect REGUA land to a previously fragmented area of forest.

As Patrick said “I’m glad I made the effort to visit you. Inspirational meeting real people making a real change through commitment and dedication. It was terrific to see first-hand the reforestation. Backbreaking work especially on some of those slopes. Your whole team needs to be congratulated! To see the growth of the reforestation over the years since replanting was also an eye-opener.”

Thanks Patrick, your appreciation is our encouragement!
        

The Orchid Cathedral

Our readers will no doubt be following new on the construction of our extraordinary Orchid Cathedral, made possible by a generous grant from the San Diego Orchid Society and Peter Tobias.  

Though progress is slow, the Cathedral will be ready for our dear friend Helmut Seehawer, set to arrive this coming April. Helmut, now 82 is to continue his inventory of the orchids here at REGUA. We are delighted because he still has the energy and all the experience in identifying the species on the mountains here at REGUA.

 To think that the total number of species of orchids in the world stands at 20 thousand of which 5% or one thousand are found in the mountains here at REGUA and environs. Bathed in cloud forest and stretching from over 2,000 metres to sea level, we can only being to appreciate how lucky we are. 

The Orchid Cathedral, a sun-screened area of 300m², will feature a rocky base, tree ferns mixed with palms, ground plants and some native small Myrtle trees, such as Eugenia sp, to which orchids will be attached. Posts will also hold some of these epiphytes. A path meandering through the house will allow visitors to see why these plants are so special, and interpretation signage will help the visitor understand the delicate role they play in nature and why so many people get excited about them. 

Should any volunteer wish to come and help us organize the interior, we would love to hear from you!!

It is getting exciting around here and already an air of expectation is setting in.

Tree planting continues at REGUA!

Using traditional methods – Fransisco and his mule (© Nicholas Locke)

Our efforts in tree planting often seem staggering, but such is our ambition at REGUA. We see degraded land as a burden to the planet and certain of our argument – that there is no way to justify the destruction of tropical forests or even search for their sustainable use. Why? We do not know how they work as an ecosystem and it erases just too many life forms that depended on it. That cannot be responsibility!! Forests and the species that depend on it around the globe are suffering and at REGUA, we are trying to grow them back. Not so easy!! 

We are so fortunate to have friends, trustees, professors, students, volunteers, staff, community members and children that also share this view. They all want to help us help us understand how it works and help us to restore the areas devoid of forest.  

This hard work provides opportunities in labour for the local community but more importantly, they gain pride in creating a more beautiful place. Responsibility is shared and though there may be a minimum that see disrespect for the hard work their ancestors put into harnessing land, today their grandchildren understand that forests teem with life, biodiversity and of course, produce water.

We have just capped half a million trees planted and we are very proud of our story.

We are especially proud of our ground team who made it possible!
