How often do monarch butterflies reproduce?
Answers
Hey mate...
Each butterfly lives from two to six weeks. The male courts the female in the air, tackles her and breeds with her on the ground. As the monarchs migrate to their summer territory, the female lays her eggs on milkweed plants. The eggs take 3-15 days to hatch into larvae.

Courtship occurs in two phases. During the aerial phase, a male pursues and often forces a female to the ground
. During the ground phase, the butterflies copulate and remain attached for about 30 to 60 minutes....
Only 30% of mating attempts end in copulation, suggesting that females may be able to avoid mating, though some have more success than others...
During copulation, a male transfers his spermatophore to a female. Along with sperm, the spermatophore provides a female with nutrition, which aids her in egg laying.
An increase in spermatophore size increases the fecundity of female monarchs.
Males that produce larger spermatophores also fertilize more females' eggs
