I don't know how to tell the difference between a comma and a question mark. Thanks in advance for any help.

Moved from Butterflies.

Question mark
On this photo, you can tell by the row of four black spots on each forewing above (one spot is oblong). In Commas, there are only three spots in these rows. In your other photo, the white "question mark" is clearly displayed on the hindwing below. In Commas, there is no white dot next to the curved white mark.

I didn't want to strictly go
I didn't want to strictly go off whether or not the dot was or wasn't connected. Thanks for the other advice though, that's why I included both shots. Both of these are common where I was.
