How do Butterflies Mate and Reproduce
After completing their developmental stages and transforming into adults, the males mate with their female partners by holding onto the female abdomen with their claspers. A few days later, the females deposit tiny eggs on a host plant. The hatchlings feed and grow, thereby completing the life cycle process.
How do they Mate and Reproduce
Reproduction in butterflies starts with a courtship display, during which a male flaps its wings briskly and emits microscopic scales that carry pheromones. These pheromones work as a sexual stimulant, arousing sexual excitement in females. Some male butterflies perch on tall plants and wait for the females to come, while others follow the pheromone trails of females to locate their prospective breeding partners.
A pair of butterflies usually sit on the ground or perch on plants and trees to mate. The members of the breeding pair join their abdomens, and the male delivers a packet of spermatophores to its partner’s body. Some butterfly species, such as the Green-veined White, can fly while mating.
Fertilization takes place just before the female is about to lay eggs. Once fertilization has occurred, the new butterfly starts to form. The female butterfly then deposits the egg on a suitable host plant. They are quite selective about the characteristics of a host plant because its quality can affect the development and survival of larvae.
- When butterflies mate, they can stay together for up to 16 hours.
- A female butterfly can lay up to 500 eggs, among which one in twenty survives and reaches its adult stage.
