were found on both streams, both males and pairs and ovipositing, but
were easy to overlook. I included the inset because I thought the pose
looked rakish.




Anisagrion allopterum. Blue trail, FEV, 8 March 2009. The last photo
was one seen at Selva Negra on 11 March, which Dennis Paulson also
identified as this species.


on blue trail on 9 Mar). Cerulean Dancer (Argia anceps) looks similar to
A. fissa and A. westfalli, but those species are apparently not found there,
and the claspers were hairy and flattish, so anceps is as close as we get.


on wet leaves or mud along the blue trail at FEV. She was tan with metallic
green darker areas; slightly flavescent wings with tan pseudostigma;
s9 and s10 pale; ovipositor extended well beyond tip of abdomen and was
pale with a narrow black rim. This also points to A. anceps; 7 March 2009.


we photographed in Panama was identified as such by Dennis Paulson.

and ovipositing, at GN, 9 March. Also found at most stream crossings at
Domitila, 12-14 March 2009.

Dusky Dancer, Argia translata, although the pattern on the tip of
the abdomen is not an exact match (I understand they are quite variable).

is an immature which looks like a Band-winged Dragonlet, E. umbrata.
However, note the uneven width of the wing bands,with the
hindwing band broader than the forewing (nice tip from Paulson).

Also near Rio Pintal, Domitila, 12 March 2009.

in Panama. Wide-tailed Sylph (Macrothemis pseudimitans),
GN, 9 March 2009.

seems sort of heavily patterned. Domitila, 12 March 2009.

Spot-tailed Dashers (Micrathyria aequalis) found on Rio Pintal within a
couple of kilometers of Lake Nicaragua, Domitila 13 March 2009.

12-14 March 2009.




The thorax isn't quite as patterned as O. ferruginea. Paulson first identified it
as Orthemis schmidti (also here) which has not been recorded for Nicaragua. Later,
he thought it must be a heavily-patterned Orthemis discolor.

Wow, back with a vengeance.
Do you keep a collection or "catch & release"? How easy/hard is it to ID them in the field - especially tropical countries?
I have a helicopter damsel from Amazonian Ecuador - would it be possible to ID from a photo of the specimen? It was quite an amazing thing to watch in flight.

The Lemon-tipped Helicopter Damsel looks massive for a damselfly!
Ted, we have a very small reference collection of local species, but in general the only ones we collect go to the University of Michigan Museum of Zoology to serve as vouchers for new locations. We did not have collecting permits in Nicaragua, so we just netted and released. There are some good references for the tropics, but we couldn't lug them all along on our trip...hence many photos of various features in the hand for later ID (there are many dozens not posted here!).
There aren't a huge number of species of helicopter damsels, so an ID is possible from a photo, send me a link and I'll take a look.
And John, the largest member of the order Odonata is one of these helicopter damsels -- I wrote about them here:
