If you are a North American and you have ever seen an earwig, the chances are very VERY good that you are familiar with the European earwig Forficula auricularia* According to my go-to insect guide, "In the early 1900s, European earwigs were introduced to Rhode Island, and quickly spread across the country." It's nice to lay the blame on a neighboring state, since Massachusetts is responsible for a great many Old World invaders.
Earwigs are essentially harmless, causing only psychic damage if--for example--they suddenly appear in from a child's toy that was left in the yard over night. I've recovered from that shock, as you can see by this photograph. The alarming "pinchers" are anatomically the same as the vibration-sensing cerci of cockroaches and silverfish. Earwigs make a show of bending those cerci at you if you try to pick one up, but apart from perhaps some large tropical species, they can't actually pinch you with them. There are a few native North American species, but I am confident I have never seen one--every earwig I've found roaming the sunflowers, or hiding in the cracks of the chicken coop, or harboring in the folds of anything made of fabric left outside overnight, has been a European.
They are opportunistic omnivores, sometimes eating aphids from your garden, sometimes damaging your garden plants, probably more often doing something entirely neutral. What they don't seem to do, despite folklore and their name, is habitually enter human ears. This gross list includes cockroaches, fly larvae, and actual parasites, but not earwigs. It may have happened at some point in history--there are a lot of humans sleeping on the ground, and a lot of earwigs out there, but it's not a typical part of their natural history.

Date: 2015-10-12 12:06 am (UTC)Fascinating critters. Those cerci that grab food ?or get waved at other earwigs for defense? made me think of the pyxies in the African savannahs with their back legs shoveling holes to sit in so they can wait for their prey to fall in.
[My captive bred pyxie is eight years old now I think. He lives alone because a frog that doesn't care for his neighbor frogs will eat his neighbor frogs].
We used to get both earwigs and silverfish that come up the bathtub drain once in awhile. Not so much anymore since I've now got a de-humidifier in the basement. And two cats on patrol.

Date: 2015-10-12 07:20 pm (UTC)I overheard a very funny conversation about earwigs in the pub once. And auld lad was saying to a guy about my age "...but you wouldn't remember earwigs. You're too young". My group of 20-something year olds tried to butt in to say we'd all seen earwigs and they still existed, but the old fella didn't believe a word of it and thought we were thinking of something else.
