"Photo of moths at mercury vapor showing "contrails" ???"
Very cool picture Mike thanks for the post - is it missing a ":-)"?
Putting on an astronomy hat Jim, I'd say "contrails" would be
scientifically a misnomer and they are just ordinary "moth trails"
(analogous to the "star trails" astronomers love to photograph) with
nothing else likely going on. If a crazed moth at a mercury vapor lamp
travels at 5 mph, it will travel during the exposure (Mike diod 1/3
sec) about a half of a yard which seems to be the case if we take the
diameter of the post in the forground as a bit larger due to
perspective of the lens. So nothing special IMO
-- except a near pun of sorts since contrails are made of upper
atmospheric vapor/ice crystals and the bulb functions using mercury
"vapor" -- ;-)
Kindest wishes
Doug

If these are not merely optic phenomena resulting from
reflection/refraction of the light off the wing scales, it may be
interesting to test various species to see if their wings have any
ability to store and then emit light energy. This then begs the
question whether or not this capability has any adaptive value to the
species or is just an accident of the materials the wings are built of.

Dear Jim,
I do not know if this will post to the list serve. If it does not,
please feel free to re-post it there.
In July of 2010 (about the 9th) my wife and I spent a couple of nights
at Manchester, Tennessee. I think we stayed at the Sleep Inn at 84
Relco Drive. The rear of that hotel faces a Quality Inn at 2314
Hillsboro Blvd. At the edge of the Quality Inn parking lot is a pole
rising about 20-30 feet at the top of which is a 3-sided enclosure
holding 1-2 extremely large lamps, probably mercury vapor but possibly
another type. The light from this structure illuminates the large
parking lot and the side of the Quality Inn.
We observed many dozens of moths flying back and forth through what I
presume to have been an electrically charged or ionized atmosphere that
might have extended 5-10 meters in front of and to the sides of the
lamp(s). The flight path of each moth looked like a streak of bright
light (nearly white or off-white) and, with so many moths being
present, gave the impression of a burst of fireworks. These "contrails"
were, I presume, the result of the collision of "charged particles"
brought about by moth flight roiling the atmosphere.
I don't believe that any moths flew into the lamp enclosure or nearer
than 2-3 feet of it. I examined the parking lot near the pole and
found no evidence of killed moths. There was no bat activity that we
observed. I did not think to take photographs.

On june 13 2012 ~ 2Am about an hour north of Hinton Alberta, I seen
what
appeared to be luminescent moths.
They would fly into a high watt halogen light then come out glowing
like hot
embers. Even when they went behind the light tower they glowed. About
the
size of a 25 cent coin. This would last about five seconds then it would
fade, and they would fly back to the light and come out glowing again.
There
where moths on the side of the building that where flat white ish with
triangular wigs but I don't know if these where the same ones that where
glowing. Is there such a things a luminescent moth? What did I see?
