Rothschild Silkmoth (Rothschildia hesperus)

Dr Adrian Spalding, president of the British Entomological and Natural History Society in company of Devon’s Marsland reserve director Gary Pilkington visited REGUA in search of insects and birds last October.    The weather was not helpful being hot and dry, so together with Jorge, REGUA’s resident lepidopterist, we headed for a night’s “moth trapping” at Bel Miller’s house in nearby Macae de Cima.

The weather at that point changed and a light drizzle started.   Bel had mentioned that the weather had also been dry so the rain was most welcome.   Before dinner, Gary set up the light and whilst we had our meal, we could see the moths homing in.   Dr Adrian was up and down and taking photographs of species that converged by the light.    Jorge patiently placed examples of Hawkmoths for identification and send mouth-watering photos to Alan Martin, co-writer of REGUA’s publication “A Guide to the Hawkmoth of the Serra dos Orgaos, South-eastern Brazil”.

A multitude of Silkmoths, Tiger moths, Hawkmoths and other micro moths as well as other insects attracted by the light and humid weather came in droves and Adrian said that this must be “the best night EVER I have mothed!”    Gary was similarly delighted, his head covered in moths busy taking photos.

A superb Giant Silkmoth visited, Rothschildia hesperus (Linnaeus, 1758).   Occurring from Argentina to South USA, this is a canopy rainforest species found from sea level to 1400m. It has a wingspan of 10-12 cm and the male is larger bearing transparent triangular windows in each wing.   Females have more rounded wings than males. The adults do not feed, for after mating and laying eggs, and their life’s function is fulfilled.

Dr. Adrian and Gary were in their element. Who wouldn’t be, covered in moths !!

3rd Dragonfly and Damselfly Tour a resounding success!

An eminent group of European Dragonfly and Damselfly specialists converged at REGUA this month to see their beloved species under the professional guidance of Tom Kompier from the Netherlands.

Tom (dressed in the National garb above) visited regularly over two years under the auspices of Rio de Janeiro National History Museum, and wrote the definitive guide book on Dragonflies and Damselflies of the Serra dos Órgãos region, identifying an amazing 204 species, one of which is new for science and will named after REGUA!

This is the third organised dragonfly and damselfly tour at REGUA and the group saw 147 species in their eight days here.   The weather in the first two days wasn’t helpful, but the group not only cherished seeing their species but loved their time enjoying the REGUA hospitality.

Thank you for coming and sharing your enthusiasm of these quality habitat indicator species!

David Nemazie of University of Maryland visits REGUA

We were fortunate to receive birders David Nemazie and René Santos at REGUA recently. David is chief of staff for Environmental Science at University of Maryland USA, and René is a super bird guide who brought him here.

The State of Maryland is twinned with the State of Rio de Janeiro with both Chesapeake Bay and Rio’s Guanabara Bay having geographical and environmental similarities. Both coastal bays have similar environmental issues due to large populations and associated problems with waste water treatment, storm water, and habitat degradation.

In 2014, the Governor of the State of Rio concerned with the Olympics in 2016 approached Maryland’s governor and asked him and the University for guidance in cleaning Rio’s Bay following their success.   Rio’s governor obtained support from INEA (RJ Environmental State Agency), UFRJ (RJ University) and other partners to provide the first step, the elaboration of the “Guanabara Bay Report Card”

The report cards ( ) have been successful in other regions and offer a snap shot of the state of the Guanabara Bay as it is today.   It gives ‘scores’ on health and condition, identifying the issues at heart.

It now is up to all of us to engage the wider public with programmes in awareness and education to help the Government define priorities and actions that will contribute to a better care for our Guanabara Bay, home to river dolphins and seahorses.

We are ready to help and do our part.


The Knight Family continue their visit

Sylvia and Chris Knight visited REGUA recently with their two children, and one of the tasks they undertook was to see how many different seeds they could find in the forest.

However, that was not the only thing they did in their visit – here’s more from Sylvia.
“As a family, some of the real highlights were our night-time walk where we were spotting caiman, opossums and nightjars as well as other sightings of sloths, a gorgeous orange spined hairy dwarf porcupine, two male blue manakins displaying to a female, watching 1743 cattle egrets come in to roost, and so much more.

We’d like to reiterate our thanks to all the people at REGUA who made us feel so welcome, and made our stay so enjoyable by ferrying us around, feeding us, finding us incredible wildlife and answering a lot of questions!

Seed Collecting Holiday!

Sylvia and Chris Knight recently stayed at REGUA with their two children.    They opted to stay in the relaxed environment of the research accommodation, and here is their review of their stay with us.

“We have just returned home after four wonderful days at the REGUA reserve.   As a family with two primary school aged children, we knew that having the chance to spend time at the reserve was going to be incredible, but was slightly concerned about how long the girls would last before they got tired or bored.    We needn’t have worried!

The combination of incredible birds, mammals, insects, plants and reptiles together with the most wonderful swimming spots we have ever encountered meant they were totally engrossed and as sad to leave as their parents were.

Having visited two other places in Rio state before arriving at REGUA, they particularly appreciated the amount of space and the freedom that gave them – for example being able to go and visit the capybara group on their own before breakfast. A mini ‘project’ for the visit was to make a seed collection – we were just short of 100 types, but I’m sure it could have been much more.
