There's a hole in my zucchini dear Liza dear Liza

In the past several years I have been super lucky with pests.  This year I redid my garden, so I got a very late start. Most of what's in the garden were store bought veggie.  I planted radish, and flowers ect.  But all of that are young seedlings.  So it isn't a big surprise I have a pest.  I looked under all the leaves, and the only thing I saw were tiny little spiders.  No way they made that big hole.  The plant still looks healthy. Just wondering if anyone has an idea of what it could be, and how worried I should be.  Thanks

My best guess would be grasshoppers.
