Earwigs - nope!
Looks to me like a very limited taste testing by a bug that decided it was not to his liking. I get that and just like that on some outdoors once in a while......generally some mean looking little spiders take up house making in the plant and bad bugs go away...
Crickets? Maybe but, I doubt it.....It's basically not a tasty plant to most leaf eaters.
Like I said, I get that a little and from time to time on outdoor plants. I would ignore it. Unless it begins to expand, rapidly....Never seems to happen to me.
