Temperatures

Very short feeding/growth seasons

Limited vegetation

Integumentary

Insulated scales: layered scales that trap heat.

Dark-colored wing veins: These help absorb any general sunlight to keep the butterfly warm.

Circulatory

Heat exchange: Warm blood flowing out from the butterfly's core helps warm the cold blood returning from its wings and legs.

Slow metabolism: The butterfly has adapted to slow its heart rate and conserve energy during the most brutal season.
