So I have a question my butterfly is eating alot no sings of scratching. I’ve seen some have this spot on them online I just wanna know if I should be worried

No, that is a normal part of their coloration that appears mostly at night or when they are stressed. Mine show that regularly.

No need to bother as it is a part of their coloration which will appear during the night mostly.
