The
Shining Moth
The
shining moth, Hyles lumens,
can be found in mainland Asia, as well as most of Japan. At a wing
span of twenty centimenters, it is one of the largest moths of the
region. But what makes the shining moth special is not its size, but
rather the scales on its wings.
Shining
moth males have a peculiar life-cycle. They come out during midday
for a few hours, and then again around midnight. During the day,
their scales, which are coated in a substance very similar to
glow-in-the-dark vinyl, absorb the sunlight. And, when they come out
again during the night, their glow attracts the females of the same
species.
This
behavior is very unusual for moths, who usually use the highly
sensitive antennas on the males to find partners. In addition,
although the light seems to attract females, it is only seen in a
rather restricted radius, and it can be a big give-away to predators.
Thus, it has been theorized that this morphological trait must have
evolved in isolated conditions, with low risk of predation and in
confined space. How the moths managed to spread as far as they have,
though, remains a mystery.
In
ancient Asian culture, shining moths are a recurrent theme, and the
people seem to believe that they are a good omen. It is even said
that some cultures have elaborate rituals centered around the moth,
either to extend ones' life, or to guide the dead to heaven.
Dr.
Louis Eclats, of the Institut des Lumieres de Paris (ILP), believes
that the moths have had a deep and lasting impact in asian culture
that far exceeds that of the occasional ritual, and that every
religion in the area has been inspired by the insects. He is also
keen on studying the moth's wings in greater detail, since the
conservation and emission of light is much more refined in these,
than in our own glow-in-the-dark objects,
