 Abstract overwintering is a critical part of the annual cycle for species living in temperate, polar, and alpine regions. Low temperature biology is a key determinant of temperate species distribution. Termites are distributed primarily in tropical regions, with only a few species found in the temperate zone. In reticular termesperitus, researchers discovered an underground chamber where the king and queen survived the winter, separate from the one they used during the warmer breeding season. The chamber was located in the roots of stumps, and the winter minimum temperature was higher than that recorded in logs on the ground. Researchers also observed that air temperatures dropped below the critical temperature multiple times, based on weather records in Kyoto spanning 140 years. These findings suggest that the reproductive survival strategies allow them to overcome environmental conditions at the latitudinal limits. This study provides insight into the termites seasonal phenology, long-term survivorship, and life cycle. This article was authored by Mamoru Takata, Takako Nishi, Shuyunogai, and others.
