THE HEATING SYSTEM
OF THE WINTER MOTH
When winter comes, many insect species inhabiting cold regions of the
world die from cold or lack of food. That is because insects are delicate
creatures, but there are some exceptions to this rule. For example, owl
moths look like butterflies and at first sight seem very delicate. In reality,
however, they are strong enough to survive tough winter conditions.
Therefore these moths are also called “winter moths”.
Like butterflies, a winter moth has two wings and a trunk to which these
wings are joined. In order for this moth to fly, the temperature of its thorax
to which its wings are joined should be 30 o C (86 o F). But the temperature
where they live is usually 0 o C (32 o F) and even drops below zero degrees
from time to time. How can winter moths survive
such cold? What prevents them from freezing
when they are motionless, and what en-
ables them to fly in cold weather?
This moth species is created together
with a special heating system that en-
ables it to live under winter conditions.
This system consists of several com-
plementary features.
