Eggplant leaf damage

[aclum]

Any guesses on who's been eating my eggplant leaves? This damage is on sort of an expendable plant that I put in one of my raised beds as an experiment (to compare with the same variety grown in a kratky bucket). The damage occurred over the course of a week or two and other than a very small dwarf sweet scarlet tomato planted nearby, none of the other plants in the bed are affected. The damaged plants are in the corner of the bed closest to a huge artichoke plant across a pathway. Thinking it might be earwigs, I put out shallow plastic cups of olive oil and soy sauce, but didn't catch any earwigs. I've also put out Sluggo Plus....

I clipped off these damaged leaves and there are several undamaged leaves higher up and a little eggplant is actually starting to form. The whole plant is probably under 6 inches tall at this point.

So any idea of what's going on and what to do about it?

Thanks!
