The blue morpho butterfly reproduces through sexual reproduction, where males and females mate to produce eggs. The female blue morpho lays her eggs on the underside of leaves, typically near the host plants that the caterpillars will feed on. The eggs hatch into caterpillars, which eventually undergo metamorphosis to become adult butterflies.
