that by there private part
i think the females would be slightly bigger as with other insects
u look at her\his wings and see if 1 is longer. if the 1 has longer wings means that is a female and the shorter winged one is a male. what school are u from?
im pretty sure it is detirmined on the color of its eyes but i dont think anyone has determined how you can tell yet
what you do is get gloves or tweezers pick it up the males have horn like things on their belly females don't wait why do you want to know
