The male Monarch has a black spot on each wing the female does not.
it is not possible to tell until the caterpillar has formed into a butterfly
easy....if its a boy it starts humping
Boy butterflies like leaves, girl butterflies like petals
You can tell the difference between a male and female Monarch butterfly by examining their wings. The male Monarch butterfly has two black spots on its wings while the female does not. The male also has thinner vein lines through its wings than the female.
dna if coloring the same for the species
I don't think you can until it changes into a butterfly or moth.
The only way to tell is to look at the admen. For girls it is slightly larger than boys since they hold the eggs.
how do i tell if my my turtle is a girl or a boy?...
it is a boy but this is a girl
you cannot tell if the caterpillar is boy or girl
its harder for a boy to tell if a girl likes him
YOu can not tell the difference between a girl or boy starfish.
