The photo at right shows a small lake near the jeep trail at Amazonia Lodge. This was the site of a number of odonates, mostly libellulids. The small stream that formed the lake passed through the forest and crossed the jeep trail near the lodge, and there stream species such as Hetaerina and Gomphidae were also seen. Although no specimens were caught, dragonflies that were probably the Aeshnidae: Gynacantha (brown aeshinds that flew rapidly up and down the jeep trail) and Libellulidae: Orthemis (defending fresh rain puddles on the jeep trail) were seen often in the vicinity. (12º52.3'S, 71º22.44'W, 500 m elevation)
At the small stream there were Hetaerina rosea (identified by Dennis Paulson) damselflies perched on vegetation alongside the water. The photo at left shows a male. The photo at the right shows the male terminal appendages of a specimen collected 12 November.
At
right is a scanned image of one of
the Hetaerian rosea specimens that shows the extent of red in the wings.
Another odonate seen at the stream was a gomphid (Phyllogomphoides sp.). Below right is a photo of a male perched along the stream in the sun. At this point the stream passed over the jeep trail. The stream here was only about 20 cm wide. The photos on the left depict the male terminalia in lateral and dorsal views.
At right is a zygopteran photographed alongside the
lake. No specimen of this species was captured. Below left is
a red libellulid, possibly an Orthemis, perched on a twig over the lake.
Finally, at below is a male damselfly (Coenagrionidae: Acanthagrion sp.) with rather strangely-shaped terminal appendages. This speciemen was taken at the outlet stream of the lake in the shady forest.
