Male and Female Monarch Butterflies

Male or Female?

Males have a small black spot on the top surface of the hindwing. Females do not.

You can see the spot when the wings are open; sometimes it's faintly visible when the wings are closed, too.

Males also have slightly thinner wing veins.

Although not evident in these pictures:

— females tend to be slightly darker than males.

— the tip of the abdomen of the male and female are visibly different.
