ATTRACTION OF MOTHS
TO LIGHT.
It is common to observe moths
flying around lights at night in the streets and houses. This frequently
involves a danger and it is not known for sure that insects can get
advantage of this behavior. There is a kind of sexual stimulation which
leads to moths to light, although some studies seem to conclude that, in
some groups, male moths would be most attracted by the light. It is
known that some species of migratory moths are traveling to other
regions as the seasons change. For this tour are guided by the moonlight
to be most nights, this lunar light makes them fly higher and this
enables them to avoid obstacles and predators, as well as take advantage
of the air currents.

Most of the species of moths is night.
It is known that the moths define their path through for
the position of the moon and the magnetic field of the land, since the
moon is very far, is a good point of reference to mark the course, it is
as if they had a compass internally. Therefore the attraction of the
moths towards the artificial light is linked by means of its guidance,
it is necessary to think that this system of orientation they use since
ago million years, whereas we use the electrical light approximately
since hundred years, to send the danger an adjustment of the moths would
needed to this new factor introduced by the man and simply has not had
time them. Also it is possible to be related to a mechanism of escape
related to the light, when a shrub is shaken where they hide some moths
go to the light by a natural reaction.
The moths detects the ultraviolet light and prefers
the lights white and bluish. The yellow lights he hasn´t got power of
attraction on them. The wavelength of light to that moths is more
sensible is the ultraviolet one, being the light used for electrical
apparatuses for the elimination of plagues of moths. A hypothesis which
it relates the permanence of these insects to flutter towards the light
is that moths takes certain time in fitting the eyes of the light to the
dark, like the humans, but in most of the insects this adjustment are
made much more slowly. Es a danger to separate from the light source
because it means to fly completely without information, also moths does
not remember the experience vivid previously and will be attracted by
another light source, being in the same situation one and again.

The attraction of the moths and butterflies
towards the light is in use for the electrical exterminators.
Recent research is discovering that before
a storm, when the air is humid, dramatically increases the number of
moths that come to the lights. In dry weather and calm, go far fewer,
and since much distance. It is believed that this phenomenon is related
to the water, particles in the atmosphere help convey sound vibrations.
In that case, they would be vibrations caused by electrical appliances
lighting, of origin thermic, or the weak sounds of the flames, Those who
would to excite some special recipients of the moths and would attract
them towards the lights. It is not known what meaning can have these
tiny sounds in the lives of these insects.
