Saw this butterfly on our farm on the Eastern shore of Maryland on the Maryland Delaware line towards Dover Delaware. I didn’t get a good look at the top side of the wings but think they were mostly yellow. I have a good shot of the underside but I seem to be finding site using different names for what this appears to be. Would love to have your take on it.

Dear Patti,
Your digital file was named “Southern Dogface” and we disagree with that identification, though the family is correct.  Though you don’t have a dorsal view, it is possible to make out the markings through the wings, and we can see a row of lighter spots in the black border of the upper wing.  It also appears that the coloration is slightly orange, indicating this is a female Alfalfa Butterfly or Orange Sulphur,
Colias eurytheme.  You can compare your image to this BugGuide image.
