Ok. So last year, I successfully grew tomatoes, cucumbers, snap peas, and a couple of green beans. This year, I put seedlings in the ground as they developed true leaves and within a week something was chewing on them and several had shriveled and died. At first it was just crawling plants but I have noticed some issues on my tomatoes and beans now too.

I finally got smart and propped the crawling plants up for now, but there is still SOME chewing going on. I have noticed opaque balls of something - hard, and they are a whitish opaque color. They start off small but grow to be about half the size of a popcorn kernel. I don't know if they are related or not but they look like something that could hatch something else....

Any ideas on what it could be/how to deal?
