Paul Hopkins and Magnus Billqvist stayed at the REGUA lodge from Jan 23 until Feb 13. During almost the first half of their trip they were joined by Agnes Ludwig and Tom Kompier. The weather was somewhat wet and cold, but nevertheless the tour turned up 152 species out of the 208 that have now been recorded from the Guapiacu catchment. The discovery of a new damsel for the REGUA list, Aceratobasis macilenta, was very exciting, but there were several other remarkable records or developments.

The swamp at the bottom of the hill on which the lodge is situated, near the office buildings, was wet throughout the stay. It is still the only confirmed site for Brown-striped Spreadwing Lestes tricolor in the area, but holds easily 25 species within its 30×15  m area. Amongst these are sought after species like the Flame-tip Telagrion longum and Brazilian Blue-eye Anatya januaria, both often found emerging there, but it now also holds a good population of Caribbean Duskhawker Triacanthagyna caribbea and the rarely encountered Silver-clouded Dragonlet Erythrodiplax laurentia. This little area is constantly evolving and never ceases to amaze.

The wetland itself is also evolving, with some of the pioneer species that were very common in previous years losing ground to species that likely require less disturbed habitat. This means that the Erythemis species, although still present, are much scarcer. Several years back Pin-tailed Pondhawk E. plebeja would pick off the flies accompanying Ode lovers at virtually every step, but now you have to search for it. Rainpool Spreadwing Lestes forficula, previously abundant and one of the commonest species, was almost completely gone. On the other hand, Guiana Spiderlegs Planiplax phoenicura is now really common and has been joined by the rarer Scarlet Spiderlegs Planiplax arachne, and previously common Bow-tailed Dasher Micrathyria catenata has been largely replaced by Square-spotted Dasher M. ocellata.

At the nearby forest fragment of Onofre Cunha, the recently described Regua Pincertip Forcepsioneura regua was still regular, and exciting as always.

The Green Trail up to the Waterfall was excellent as usual. It turned out to be a particularly good year for the Long-tailed Bromeliad Guard Leptagrion perlongum with dozens seen at the beginning of the trail. Further up a copula of Cinnamon Flatwing Heteragrion sp. was a first, and even more exciting was that is was seen to subsequently oviposit in a shallow forest stream, verifying its suspected habitat.

The fishponds at Vecchi remain excellent, although the Large Pond seems to suffer from disturbance. This possibly explains the apparent complete absence of Slender Redskimmer Rhodopygia hollandi, which used to be a common species here. During our visits we observed a very late Green Forceptail Phyllocycla pallida, which previously had not been recorded after early December. A female Silver-clouded Dragonlet Erythrodiplax laurentia here was another surprise. The small ponds again turned up such excellent species as the enigmatic Mantled Skimmer Edonis helena.

One of the most exciting observations was done at the Tres Picos area, where several Chagas’s Emeralds Neocordulia carlochagasi was observed patrolling. This area appears to be a good location for this rare species, with observations in several years now. Another specialty of this area is White-fronted Sylph Macrothemis capitata, which has now been found consistently for several years at the start of the trail up.

Although not achieving the maximum score of the 2018 tour (166), partly because fewer locations were visited and partly because of weather and luck, the result proved once more that any visitor in the right season can expect to see more species of dragonfly here than recorded from the whole of Europe, and with much more ease.
