Energy metabolism measurements taken from winter moths at rest
clearly reveal this equilibrium:
For example, a winter moth that had consumed 6 grams of plant
sap and sugar could remain at rest for 193 days at a temperature of -
3°C (26.6° F). When the temperature was increased by 3°C, in other
words at 0°C (32°F), the moth was able to continue for only 24 days.
At 10°C (50°F), its energy reserves are enough for only 11 days. 40
That moths make very accurate and rational selections is an im-
portant point that needs to be borne in mind.

Stage 5: The Special Heat Insulation System in Winter
Moths
It is well known that a heat radiates from warm environments to
colder ones. For that reason, the moth's raising its body temperature
alone is not enough to let it take flight, because the temperature dif-
ference between the moth's warm body and the outside cold will lead
to an acceleration of heat loss. For the moth to be able to take flight,
therefore, it also needs a means to protect the heat it generates. Its
body has again resolved this need with a perfect design.

Can the Winter Moth Insulate Its Heat?
Insulation is the most effective method against cold. In colder cli-
mates, buildings are constructed using insulation technologies that
reduce heat loss from external facings, windows and roofs to a mini-
mum. In a similar way, moths have an insulating system that mini-
mizes heat loss—a thick, scaly layer that covers their bodies.
