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 30oC (86oF). But the temperature
where they live is usually 0oC (32oF) 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 enables them to fly in cold weather? This moth species
is created together with a special heating system that enables
it to live under winter con
