cause the perfectly designed system in its body overcome every diffi-
culty.
This system prevents heat being dissipated to colder regions out-
side the thorax, serving as an ideal means of insulation in protecting
the moth's internal heat.
George R. Silver, of the US Army Research Institute of
Environmental Medicine in Massachusetts, conducted a series of
studies on the subject. He used an infra-red camera to photograph
these insects and observe the amount of heat they gave off. His pic-
tures showed that during warming, flight and post-flight cooling, the
winter moth's legs, wings and stomach regions warmed up very little
or not at all.
Silver's research also revealed another miracle mechanism in the
winter moth: an insulation system that delays the flow of heat to the
head and stomach regions and totally prevents heat transfer to ex-
tremities like the legs and wings. Thanks to this design, preventing

The winter moth's audi-
tory organ lies inside its
air sacs, which work as
perfect heat insulators.
One can compare the
sacs to double-glazing
on windows, since
these sacs prevent a
transfer of heat be-
tween the external and
internal environments,
thus forming a kind of
insulation wall between
the warm chest region
and the colder abdo-
men.
