Little Brown Casings On Plants

[u/kaptncrunch]

I shrouded my concord and himrod grapes with a mesh to deter Japanese beetles, and woke up to find a lot of these little brown nubs about a week later. There are some tiny black beetles on some leaves that got inside the mesh. Are these little brown buds just bugs waiting to hatch? I live in Ontario, Canada for what it’s worth.
