There's no single butterfly species called "red butterfly." Butterflies come in a huge variety of colors, and many species have red in their wings!

To tell you what kind of red butterfly you're thinking of, I need more information. Could you tell me:

* Where did you see the butterfly? (Country, region, even a specific garden or park)

* What did the red look like? (Bright red, dark red, reddish orange, etc.)

* What other colors were on the wings?

* Was there any specific pattern on the wings?

With more details, I can help you identify the specific red butterfly you're looking for!
