Tulip poplar leaf holes

We have noticed all our tulip poplars and all poplars in NWC have their leaves riddled with holes. I see no insects. Other than the holes the leaves are in good shape for now. I have seen photos of leaves with yellow poplar weevil damage. These are not the same. There is no browning of the leaves around the holes. Any info would be appreciated.
