How do butterflies mate?

Generally speaking, male butterflies appear earlier than female butterflies. After that, the male butterfly flew everywhere, looking for the newly hatched female butterfly and catching up with her first. If the female butterfly perched on a leaf has copulated, when the male butterfly flies, it will spread its wings flat, and its abdomen will rise high and never take off. This is a sign that the female butterfly does not accept copulation, so the male butterfly flies around for a while and has to give him up. On the contrary, it is mating. Sometimes, when a female butterfly doesn't need to mate, she may meet several male butterflies chasing after her mate, holding her down, flying around in circles, inextricably linked, and ascending together. At this time, the female butterfly suddenly lowered her wings and landed quickly. This escape made the male butterfly lost his way, and she didn't know where the female butterfly was before she could get away. This "escape" instinct of the female butterfly is quite interesting.

There are also some butterflies, such as most species of Seriphidae. After mating, a variety of mating derivatives (petals) grow at the base of the mating sac opening, which becomes an obstacle to prevent mating again, and there are many kinds of insects. This is a major feature of identifying insect species.

Butterflies mate with their tails touching each other and their heads facing both ends, such as Papilio. In the process of mating, if disturbed, the female butterfly will fly actively, while the male butterfly will quietly hang upside down and let it fly away.
