during cold winter inscet fell cold Nes or No

Insects can feel the changes in temperature around them. But this does not affect them the way it affects mammals. They do not get physically discomforted by the cold or hot. However, in case the temperature goes below 0⁰ F, they might go down in the ground where the temperature is slightly warmer. There are some insects which die at very high and very low temperatures.

Hope this helps.
Regards.
