Overwintering as eggs: Some insects lay eggs that can thrive through the cold temperatures. When warmer temperatures hit, the eggs will begin to expand and hatch.
Overwintering immature stages: Some insects will overwinter in their immature stages such as the nymphal, pupal or larval stage. The mayflies we experience in the spring time will do this. The nymphs of the mayflies will live and actively feed in cold water beneath ice, growing all winter to emerge in the spring. Some insects will go through a larval stage and can replace the water in their body with glycerol which is a type of antifreeze. Some will burrow deeper into the soil, layers of snow on the ground will work as insulation and keep the ground warmer from really cold temperatures.
Adult hibernation: Many insects are capable of hibernating in their adult stages. Similar to larval stages, some adults are able to replace the water in their body with a type of antifreeze. Bees will remain in their hive and can increase temperatures by using body heat or vibrating their wing muscles. Wasps and mosquitoes will seek out a protected spot and will become dormant in the winter.
Fluctuating cold temperatures that we are experiencing now are giving insects a hard time to function. Keep in mind that in temperatures such as these, sometimes the best places for insects are in your home. There is no off season for bugs, with this subject I think it's important to keep your home or business professionally protected year-round. Call me and I am more than happy to tell you more
