In temperate regions of the northern hemisphere where cold temperatures are expected seasonally and are usually for long periods of time, the main strategy is freeze avoidance. In temperate regions of the southern hemisphere, where seasonal cold temperatures are not as extreme or long lasting, freeze tolerance is more common. [ 2 ]
They are known to inhabit cold temperate forests to glaciers and the edges of ice sheets. Their optimal living temperature is between 1–4 °C (34–39 °F). They can be killed at colder temperatures due to ice formation in the body, so when the temperature drops below their optimal range they survive by living under snow pack near the soil. [8]
Prenolepis imparis, commonly known as the winter ant, false honey ant, or false honeypot ant, is a species of ant in the genus Prenolepis. [1] The species is found in North America, from Canada to Mexico , nesting deep within the ground.
These ants are renowned for their ability to survive extreme conditions. They do not hibernate, but can survive cold conditions, although this is costly to fire ant populations as observed during several winters in Tennessee, where 80 to 90% of colonies died due to several consecutive days of extremely low temperatures.

This week is going to be a scorcher — with 100-plus temperatures in the forecast all week. We asked a professional exterminator if they’d gotten more calls about wayward insects because of the ...
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
This specialized fungus can no longer reproduce on its own and needs the ants to survive. The fungi produce gongylidia, which are like little nutrient-filled powerhouses for ants.
Meteorologists issued urgent warnings about dangerously cold winds and temperatures in North Dakota and Alaska on Friday night and Saturday. In portions of both states, wind chills could reach as ...
