Between September 22 and October 6 we did another survey of dragonflies and damselflies at REGUA and its immediate surroundings. 18 new species were added to the list for the Guapiaçu catchment, taking the total for this year to over 150 species, a testimony to the fantastic diversity of the ecosystem. Just in the wetlands next door to the lodge, already more than 60 different species can be found. Below we introduce just a few of the findings.
With the advent of spring the Gomphidae returned to the scene. A spectacular find was a dragonfly that may be the first recorded male of Praeviogomphus proprius. It will be studied further at the department of entomology of the Museu Nacional in Rio de Janeiro, thanks to the support of Prof. Alcimar do Lago Carvalho for the project. Praeviogomphus previously was only known from one female and from a few larvae. Other spectacular new gomphids were two species of Phyllocycla. Aphylla molossus, a large gomphid was also found regularly again.




Another great find was a species of Castoraeschna that may be new to science. This lovely dragonfly was found patrolling the bogs at Salinas, in the mountains above the lodge. Nearby an intriguing female Leptagrion was found that also still needs to be identified.
Tiny and elusive Peristicta jalmosi, only recently described, was found inhabiting a stream close to the old wetland, where males were hanging from the tips of leaves of trees in shady parts low over the water. These damsels are so small that they become next to invisible the moment they start flying. The fact that they perch in dark shady places obviously does not help either, so possibly it has been overlooked in the past.


The trails turned up two new species of Heteragrion. This fantastic genus of beautiful and big damselflies keeps on turning up new species that are often as localized and rare as they are spectacular. The specific identity of these two species still needs to be confirmed and it is well possible they are as yet undescribed. So far this year this fabulous genus has turned up seven different species, the commonest of which is H. aurantiacum, which can easily be seen at streams around the lodge. Another more regular, if uncommon and difficult to find, species is H. consors.


Clearly amongst the many attractions of REGUA is also a fantastic Odonata fauna.
