Scalloped Oak Larvae?

Observation - Scalloped Oak Larvae?. Description: Found in the back garden yesterday on a red leaved garden shrub (Physocarpus opulifolius 'Diablo'), at 34mm it's a bit short to be Scalloped Oak which would normally be on the wing or at least a pupa by now but it's the best visual match I could find.
