In the Arctic
It would be very difficult for us to withstand the
freezing winters, strong winds, and short summers
of the Arctic. However, a few butterflies and moths
live there all year round. They have special survival
features such as antifreeze in their blood, and dark
colors to absorb heat quickly.
Summer flier
This Arctic clouded yellow butterfly flies when
the Sun is shining. As soon as the clouds come
out, it seeks shelter. A special liquid in its blood
keeps it from freezing, like the antifreeze in
a car’s radiator.
When temperatures
fall below freezing,
Arctic pupae remain
safe inside protective
silk cocoons.
The long hairs
on its body help
to keep the
butterfly warm.
