Like everyone said, it’s an earwig, a female one. Earwigs are usually predators. However, they don’t have a picky diet and can eat fruit & flowers or even rotting insects parts. Given the size of the hole compared to the size of the insect and the recently-eaten look of the wound, there’s no way the earwig did that much damage alone. Notice the angled mark at the top of the wound. That makes me more likely to think the damage was a bird, and the earwig came along to feast on the damage. I have lots of earwigs on my property, and have never seen them on any of my garden plants, though I find them hanging out in the rotting parts of various wooded shrubs along with other insects.

Earwigs! Yuck! They eat my peaches… Common backyard pest and creepy crawly, looks nasty. They hide in tiny cracks because they are so thin they can crawl anywhere.

that insect you found is an earwig. i have never seen them on a tomato plant before . but they are a pest. they eat your crops! as much as i love insects i would spray them.

It looks like an earwig (pincher bug).

Looks like an earwig. You can look it up on Wikipedia.

Looks like earwig (dermaptera) and yes, Sevin should take care of it. http://www.entomology.wisc.edu/diaglab/hilites/a3640.pdf

Looks like an earwig. I wouldn’t put poison on anything, these guys probably didn’t bite the tomato, but instead came along after somebody else opened the fruit. Putting out poison hurts everybody… and should be considered a last resort, on the order of “mutually assured destruction”.

Don’t know, but a little Sevin will take care of them. Buck
