Pytho americanus
Kirby, 1837
dead log beetle
Pytho americanus is a of dead log beetle in the Pythidae. It is native to North America, with records from Canada and the northern United States. The species exhibits notable cold adaptations, including the ability to overwinter in both larval and stages and the synthesis of glycerol during cold acclimation. These physiological traits allow it to persist in climates with severe winter conditions.

Overwinters as both larva and , indicating flexible timing that may vary with environmental conditions.
More Details
Cold tolerance physiology
Pytho americanus synthesizes glycerol during cold acclimation. Glycerol acts as a cryoprotectant, lowering the freezing point of body fluids and protecting tissues from cold damage. This biochemical supports survival in subzero temperatures.
