Nest Architecture and Thermoregulation in Social Insect Colonies
Quick fact
Some termite mounds maintain internal temperatures within a narrow 30°C to 31°C range during the heat of the day, even when outdoor temperatures swing from 10°C at night to 45°C at noon—a feat that would require sophisticated HVAC technology.
Why this is interesting
Imagine a skyscraper that heats and cools itself without any electricity. That's exactly what a termite mound is—and it's built by insects smaller than your thumb.
