That's a very nice butterfly,at my school we are raising some monarchs too. How long have you had him?
He's a boy! by: Sharon
Don't know if you knew that Stanley actually is a boy. See the black spots on each rear wing? The females don't have these spots. I learned this when my daughter and I did her science fair project on Monarchs and we raised one. Hers was a girl. She'd named the caterpillar Fred, so had to change its name after it emerged.
