Photo at right by David Pantle - showing the author intently stalking Aeshnidae on the mud flats at Huacarpay Lakes (13º36.71'S, 71º44..21'W, approx 3000m elevation) near Cusco. Males flying 6" to 18" above ground, apparently searching for females. Saw several pairs in copula. Caught specimens of males, but no females were taken. 5 Nov. 2000.
At left and below are lateral and dorsal views of the Aeshna species from Huacarpay Lakes. Photographed 5 November 2000 by Roy Beckemeyer. This site on the high and dry eastern slopes of the Andes. Identified as Aeshna diffinis by Dennis Paulson, but based on Nathalia von Ellenrieder's recent article in Odonatologica ("A synopsis of the Patagonian species of the genus Aeshna Fabricius (Anisoptera: Aeshnidae)", 30(3):299-325), it appears that the species may be A. absoluta.
This picture shows an aeshnid perched on the south-facing vertical surface of one of the huge rock walls of the Sacsahuaman ruins overloooking Cusco at nearly 3500 m elevation (13º29.65'S, 71º58.44'W). These were flying around about a meter above the ground and then perching 2-3 m high on the walls in the sun. I was unable to take specimens or to get close enough for a good photo - this one taken with a 400mm f5.6 telephoto.
In the cloud forest along the Atalaya Road along a small trickle coming down the hillside (13º10.7'S, 71º36.57'W, 2600 m elevation), I got my first look at a Gomphomacromia. This is probably G. fallax, if one goes by the records of what has been found in Peru, but I have no good data on the species that allows me to say for sure at this point. (Dennis Paulson has identified my specimens as Gomphomacromia cf. fallax.) I have included a scan of the wings of a specimen. Below are photos of a Gomphomacromia male perched at a second site (13º2.58'S, 71º35.7'W, 1500 m).
The site is one where there was a mossy cliff with water trickling down it (photo below right). Here I also saw a female flying along the cliff face and flicking her abdomen toward the moss as if she was ovipositing. I did not capture the female, but have a single male specimen from each site.
