Aquatic insects have developed freeze tolerance much like their terrestrial counterparts. However, freeze avoidance is not an option for aquatic insects as the presence of ice in their surroundings may cause ice nucleation in their tissues. [15]: 148 Aquatic insects have supercooling points typically around −3º to −7 °C.
Insects that do not migrate must halt their growth to avoid freezing to death, in a process called diapause. [2] Insects prepare to overwinter through a variety of mechanisms, such as using anti-freeze proteins or cryoprotectants in freeze-avoidant insects, like soybean aphids. Cryoprotectants are toxic, with high concentrations only tolerated ...
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 breed of amphibian has two pairs of webbed feet, which allows it to have a bit of hang time. ... If an insect attacks a tree, it will fight back. ... They can actually let their bodies freeze ...
Insect activity increases when the weather warms up. Insects can make it difficult for reindeer to gain the weight they need to survive the winter. The tundra is changing as well.
Freezing of the head and thorax in other insects tends to have adverse effects on neural tissue, so it is not surprising that these protective mechanisms have been observed in certain species, but E. nugatoria is the only insect known to semi-freeze through the winter. By allowing the abdomen to freeze, evaporative water loss is reduced over ...
Wētā is a loanword, from the Māori-language word wētā, which refers to this whole group of large insects; some types of wētā have a specific Māori name. [2] In New Zealand English, it is spelled either "weta" or "wētā", although the form with macrons is increasingly common in formal writing, as the Māori word weta (without macrons) instead means "filth or excrement".
