How do butterflies reproduce?
They mate, joining the tips of their abdomens, and the male passes sperm to the female in order to fertilize her eggs. The female then lays her eggs on plants or on the ground. Generally, female butterflies choose which males they want to mate with and males therefore compete for the attention of females.
Do butterflies have internal organs?
Yes, butterflies and all other insects have both a brain and a heart. The center of a butterfly’s nervous system is the subesophageal ganglion and is located in the insect’s thorax, not its head.
