Interestingly, it may actually be leaves. If you remove the cowl cover and look inside (from outside the car with the hood open) you will see that the blower fan is open to the exterior and all kinds of stuff can fall in there if it's small enough to fit thru the grids in the cowl. As for the cabin filter, it is unfortunately downstream of the blower, which means it will keep stuff out of the cabin, but the blower itself is exposed to whatever can fall in there. Not a very elegant design.
