Is it a boy or a girl??
When your monarch emerges, it is quite easy to find out if you have a boy or a girl.
IT'S A BOY!
This is a male monarch butterfly. You can tell by looking at the hindwings. The stripes are narrow compared to the female and there are two very distinctive black pouches on each hindwing.
IT'S A GIRL!!
This is a female monarch butterfly. The stripes on her hindwings are wider than the male and they lack the pouches on the hindwings.
