One of the pages I follow on FaceBook is Southern Piedmont Natural History. It is maintained byt USC-Spartanburg. Today, they posted this picture:

• A – Swamp White Oak (Quercus bicolor)
• B – Southern Red Oak or Spanish Oak (Quercus falcata)
• C – Chinquapin or Yellow Chestnut Oak (Quercus muehlenbergii)
• D – Sawtooth (Quercus acutissima) is a non-native oak introduced from Asia in 1862.
• E – Northern Red Oak (Quercus rubra)
• F – Swamp Chestnut or Basket Oak (Quercus michauxii)
• G – Cherrybark or Swamp Spanish Oak (Quercus pagoda)
• H – Post Oak (Quercus stellata)
• I – Water or Paddle Oak (Quercus nigra)
• J – Eastern White Oak (Quercus alba)
• K – Overcup Oak (Quercus lyrata)
• L – Willow Oak (Quercus phellos)
• M – Pin or Swamp Oak (Quercus palustris)
• N – Rock Chestnut Oak (Quercus montana)

This is very interesting to me. I have never been able to identify the different varieties and I love having this reference.

They pointed to this website as a place to learn what insects are supported by the oak trees in your area. https://nativeplantfinder.nwf.org/About

I have made a separate page with the article from FB because it’s long. But, also more informative.
