A dozen flat brown bodies scatter when a flowerpot lifts. Pincers raised like tiny scorpion tails. Everything about the name tells you what you need to know. Earwig. A creature that crawls into ears and lays eggs in brains.
The name comes from an Old English word for the shape of the wing, not from anything the animal has done to anyone's skull.
I'm a European earwig. I'm not venomous. I don't carry disease. I have not once crawled toward a human ear on purpose.
The pincers are called cerci. Males have curved ones, females have straight ones. They're used for folding my wings — which are pleated into an origami pattern so complex that engineers have studied it — for courtship displays, and occasionally for grabbing small prey. If you pressed me between your fingers, I might pinch. It would feel like a fingernail poke. It would not break skin. No venom, no stinger, no toxin. The most weaponized-looking part of my body is cosmetic.
Here is the part that changes everything.
I am one of the few insects on this continent that takes care of her young. After mating in autumn, I dig an underground chamber and lay thirty to sixty eggs in a tight cluster. Then I stay. I stand over them for two months through winter, turning each egg individually, licking the surface to apply an antifungal compound my body produces. If a predator enters the chamber, I face it with my cerci raised. If something scatters my eggs, I gather them back into formation. I do not eat during this period. I do not leave.
When the nymphs hatch — translucent, tiny, already shaped like me — they stay underneath my body. I regurgitate food for them. I defend them through their first and second molts. Only then do they leave the chamber to forage on their own. Few insect species show this level of maternal care. I am among them.
I spend my nights eating aphids. I eat mites, moth eggs, and slug eggs. The same gardeners who remove me often wonder why their aphid problems keep getting worse.
- Leave me in the garden — I'm a net benefit to plants at normal population levels
- Don't spray mulch beds with broad-spectrum pesticide — it removes me along with the pests I was eating
- The pincers are a bluff. The name is a myth
I've been in the mulch for years eating the aphids that would have damaged the roses. Nobody noticed.
That's because I'm good at my job.
