Based on the convex am line and location of the Vladimir Izersky image, I feel that specimen is more likely the recently (March 2009)
described species Dysdaemonia australoboreas.

HABITAT:
This species flies on both sides of the Andes,
but seems restricted to lower elevations.
FLIGHT TIMES AND PREFERRED FOOD PLANTS:
Larvae feed upon
Red silk cotton tree (Bombax ceiba), White silk cotton tree
(Ceiba pentandra) and Chorisia
In Costa Rica there
appears to be at least two broods with moths on the wing from May
through August.
Robert Lehman reports them on the wing in Honduras in
February-March-April.
FGS reports flights in February and May in French Guiana.
Jason Weigner reports a January flight 20-25 km W of Santa Cruz, Bolivia.
Lorenzo Comoglia reports an April flight in Alluriquin, Pichincha, Ecuador.
Brian Fletcher reports a February flight in El Oro, Ecuador.

ECLOSION, SCENTING AND MATING:
Males use their antennae
to locate females at night by tracking her airbourne pheromone plume.
EGGS, LARVAE AND PUPAE:
Eggs are apple
green when first deposited but shortly turn red, maintaining a
white-cream coloured equatorial line.
The incubation is short in the tropical heat and lasts only six
days. | 
|
Early instar larvae are well adorned with thoracic
and anal horns and colouration is that of a bird dropping.
I am convinced there is either an external intelligence or an internal
one that provides for camouflage.
|  |
This third or fourth instar larva has picked up
the rust-brown colouration of host stem junctures and may well hide
in their proximity during the day.
Yellow dorsal and lateral lines match the main leaf stems in
colour. |  |
Larval images are courtesy of
Dan Janzen.
The "horns", before their departure in the final instar,
are coloured as and are the thickness of main stem veins. |
|
In the final instar larvae are very plump and
dorsal and lateral lines are perfect thickness and colour to match
central leaf veins on Ceiba pentandra. |
 |
Larvae descend tree trunks at maturity to pupate in subterranean
chambers. Larvae that pupate during the summer can eclose as moths in
as few as sixteen days.

Listed below are the primary food plant(s) and alternate food
plants listed in Stephen E. Stone's Foodplants of World
Saturniidae. It is hoped that this alphabetical listing followed
by the common name of the foodplant will prove useful. The list is
not exhaustive. Experimenting with closely related foodplants is
worthwhile.
Bombax ceiba

The pronunciation of scientific names is
troublesome for many. The "suggestion" at the top of the page is
merely a suggestion. It is based on commonly
accepted English pronunciation of Greek names and/or some
fairly well accepted "rules" for latinized scientific names.
The suggested pronunciations, on this page and on other pages,
are primarily put forward to assist those who hear with internal
ears as they read.
There are many collectors from different countries whose
intonations and accents would be different.
Some of the early describers/namers chose genus
and species names indicating some character of the insect, but more
often, they simply chose names from Greek or Roman mythology or
history.Those species names which end in "ensis" indicate a
specimen locale, and those which end in "i", pronounced "eye", honour
a contempory friend/collector/etc.
I do not know the source of the genus
name "Dysdaemonia" chosen by Hubner in 1819. It could be a
combination meaning 'bad spirit'.
The species name "boreas" is the Greek god of the North Wind who
lived in Thrace. He is depicted as being winged, extremely strong,
bearded and normally clad in a short pleated tunic.
