Boy butterflies like leaves, girl butterflies like petals
easy....if its a boy it starts humping
dna if coloring the same for the species
I don't think you can until it changes into a butterfly or moth.
it is not possible to tell until the caterpillar has formed into a butterfly
The male Monarch has a black spot on each wing the female does not.
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
can you tell if a fish is a boy or girl by the tail
its harder for a boy to tell if a girl likes him
YOu can not tell the difference between a girl or boy starfish.
