Two new queens. Not sure if they're the same species

Okay, so I'm fairly certain both of these ants are Solenopsis Invicta. But I'm new to the hobby and it's throwing me for a loop. The one on the cotton ball is the one I'm like 100% sure is a Solenopsis Invicta but the one on the paper is about 1 maybe 2 MM larger than the other and has slightly different colors. I caught them both today in a parking lot about 10 yards from each other. Also, I know if it's a Solenopsis I don't have to feed her until she lays her first eggs but if they're not both the same can you let me know if she needs to be fed or not.
