How can you tell?
If you were a Monarch, there is a difference in the way boys and girls look!
The main differences include:
- Girls have thicker black stripes (it’s their veins!)
- Boys have a little spot on their hindwings (like an inkblot!)
- Side note, these are actually scent-glands to attract the female butterfly!!
Guess which is which?

The boy is on the left, the girl on the right.
Now you know!
