Insects that live under the water have different strategies for dealing with freezing than terrestrial insects do. Many insect species survive winter not as adults on land, but as larvae underneath the surface of the water. Under the water many benthic invertebrates will experience some subfreezing temperatures, especially in small streams.
Freeze-tolerant insects, like second-generation corn-borers, can survive being frozen and therefore, undergo inoculative freezing. [4] Hibernacula range in size and structure depending on the insects using them. [5] However, insect hibernacula are generally required to be: Well-insulated from extreme temperature changes [3] Protected from ...
There is a rapid cold hardening capacity found within certain insects that suggests not all insects can survive a long period of overwintering. Non-diapausing insects can sustain brief temperature shocks but often have a limit to what they can handle before the body can no longer produce enough cryoprotective components. The common fruit fly

Can the polar vortex really kill off much of this invasive species?
A bee keeper offers tips for gardeners.
Insects that are psychrotrophic can survive cold temperatures through several general mechanisms (unlike opportunistic and chill susceptible insects): (1) chill tolerance, (2) freeze avoidance, and (3) freeze tolerance. [32] Chill tolerant insects succumb to freezing temperatures after prolonged exposure to mild or moderate freezing ...
Belgica antarctica not only tolerates, but also requires a freezing climate to survive: exposure of larvae to such mild temperatures as 10 °C is enough to kill them within a week. [7] Exposure to temperatures of 30 °C kills individuals in a few hours. [8] It can, however, resist partial desiccation, surviving the loss of up to 70% of body ...
