Some monarchs are killed by frost on their wings.
This butterfly is a victim of one of these freezing events and will
not survive. The frost crystals mortally wounded the butterfly.
They penetrated through the cuticle and disrupted the cells. Although
millions of monarchs may fly out of the colony on sunny days to
find water to drink, almost all of them manage to fly back into
their colonies. Only a few get stranded in open areas where they
may freeze to death.
