Earwig
(Various scientific names)
Do not squash them! When they are crushed they emit a foul odor. They are identifiable by the pinchers on their back, which are used to hold prey and as defense mechanisms. While they are not harmful to humans, they are harmful to your garden.

| Food: | Live or dead plants, insects. European earwigs have been observed feeding on honey in beehives. |
| Biology: | Earwigs are active at night, hiding during daylight hours in moist, shady places, under rocks and logs or in mulch. They cannot survive long periods of dryness. They have a bad odor when crushed, and some species can squirt a foul smelling liquid. The forceps may be used to hold prey and for defense. They have 4-5 nymphal instars. Females lay 30-55 eggs the first time, depending on the species. Sometimes later layings are much smaller in number. Earwigs typically occur in groups. Development takes between 40 and 80 days, depending on the species. |
