The rose bushes in our garden appear to be going through a difficult age. Each time I walk by, I notice more large red "pimples" swelling up from their leaves.

To my surprise, when I poked one of these "pimples", it popped right off the leaf. Curious to know what, if anything, was inside the gall, I dissected it.

Inside, I found the culprit. A wasp larva (
probably Diplolepis sp.) was growing inside the gall, feeding on the soft tissue of the walls.
