One of the largest and most striking of the butterflies to be found flitting through 'Butterfly Journey', blue morphos have a wingspan sometimes exceeding 15cm.

Their dazzling, iridescent blue sheen is created by the diffraction of light off the millions of tiny scales covering their wings. In the wild they flash their wings to startle predators, giving them an extra fraction of a second to beat a hasty retreat.

The Blue Morpho is one of the butterfly species that we breed regularly. Our Horticulture & Botany team grow peanuts in their greenhouses and then supply them to our butterfly keepers once they are about 30cm tall. These are then placed in the Butterfly Journey habitat for the adult butterflies to lay their eggs on.

The whole life cycle from egg, through caterpillar and metamorphosis (in a pupae), to adult butterfly takes around four months. Blue morpho caterpillars and pupa can usually be seen in the Butterfly Journey breeding room and ‘puparium’.
