There's no butterfly species known as a "Lotis Blue". It's possible you're thinking of a different species or have a misspelling.

To help me find the right butterfly, could you please provide more information?

* Do you have a picture of the butterfly?

* What region or country did you see it in?

* Do you remember any other features like its wingspan or color patterns?

Once I have more details, I can tell you what this butterfly eats!
