Earwigs



When I moved into my apartment I had some earwigs living with me. They look creepy but I grew quite fond of them. 

Here are some interesting facts about earwigs.

Many earwig species display maternal care, which is uncommon among insects. Female earwigs are known to take care of their eggs, and even after they have hatched as nymphs.



Earwig fossils have been found dating back 208 million years.



The name may be related to the old wives' tale that earwigs burrowed into the brains of humans through the ear and laid their eggs there.



Earwigs rarely fly, even though they are capable of flight.



Earwigs are harmless to people.



The eggs and nymphs are also cannibalized by other earwigs.



The male and female will live in a chamber in debris, crevices, or soil. After mating, the sperm may remain in the female for months before the eggs are fertilized. From midwinter to early spring, the male will leave, or be driven out by the female.



If the mother dies before the nymphs are ready to leave, the nymphs may eat her.
