Hello! There have been some irregular holes chewed on my crookneck squash bushes (I say bushes, but they're still quite young). My burgundy amaranth also shows some evidence of chewing. I've tried to find the insects responsible, and today I saw some small, barely noticeable tiny gray insects. They jumped when I tried to squish them, so I think they might be flea beetles. However, they don't look like any flea beetles I've seen in pictures, so I'm wondering what they are and what to do about them. Or are they springtails, as seen here: https://www.vegedge.umn.edu/pest-profiles/pests/springtails?  I'm very nervous that they will destroy my squash, and I'm slightly concerned about my amaranth, too. For some context: I'm in Minneapolis, with loamy, slightly acidic soil. My garden is host to the squash, amaranth, timpsula (just popping up), hopniss, wild strawberries, prairie onions, showy wild garlic, and fledgling blueberry and raspberry bushes The only plants with damage are my squash, amaranth, and a tiny bit on the hopniss. Any help you can provide would be much appreciated!
