I have a garden mystery. I went out to pick blackberries and saw these white shavings on a leaf. Could this be some kind of hollowing activity by a stem-nesting bee? If you zoom in there is some yellow mixed in with the white and I'm wondering if that could be dropped pollen? Or maybe I'm completely off track - hoping someone on here might know!
