A group of dragonfly enthusiasts from the Netherlands, Denmark and Sweden occupied the lodge at REGUA between 5-20 January to look for dragonflies and damselflies with Tom Kompier, the author of our field guide on these winged gems – A Guide to the Dragonflies and Damselflies of the Serra dos Orgaos, South-eastern Brazil.

REGUA is one of the world’s best dragonfly hotspots in terms of diversity, and the group was not disappointed. With a total of 166 species seen, the tour even surpassed previous tours.

Not only were there second records of Lestes tricolor and Micrathyria spinifera, and good views of the critically endangered Minagrion ribeiroi and its rare cousin Minagrion waltheri, the group also managed photos of two species not previously documented with photos in nature. Edonis helena is a rarely seen small dragonfly from northern Argentina only recently known to extend into Brazil. A small population occurs in the area. The second was Macrothemis capitata, rediscovered by Tom several years ago at Salinas, but now found in the The Três Picos State Park at the top of our watershed.

Best of all, the group found two species new to the reserve list. The first was an exciting tiny damsel, Nehalennia minuta, found at the old wetland in the reserve. This species occurs widely in South America, but is not often found. And the second was Progomphus virginiae, a beautiful little gomphid found at a forested rocky stream, described from Santa Catharina State. The reserve odonata list now stands at 207 species!
