A worldwide community photographing and learning about wildlife
Found on the women's bathroom wall at Confederate Park in Belton, Texas just meters from Belton Christian Youth Center. Park runs along Nolan Creek and I-35. Majority of the landscape is made up of manicured lawn and parking lots with oaks and pecans as the dominant species.
I agree with Walnut Sphinx. I have suggested an ID with a reference link so you can check out other professionally identified Walnut Sphinxes.
