The insects in the photos are probably sawfly larvae. There are many species and the larvae are notoriously difficult to identify. This is partly because the appearance of many species changes remarkably from one instar (molt) to the next.

We'd need to see sharp photos of the entire plant (preferably when it's in bloom) to identify it.
