Butterfly farming is a method of harvesting butterfly chrysalises from the butterfly host plants. The female will only lay her eggs on her host plant or plants. Butterfly farms maintain host plants, such as tropical plants, for different butterfly species and the captive butterfly population lay eggs on these plants. The eggs are then reared to the pupae stage for shipping.
An adult butterfly lays an egg; the egg hatches into a caterpillar or larva; the caterpillar grows to form the chrysalis or pupa; and the chrysalis transforms into a butterfly.
Cocoon: An outer wrapping made by the caterpillar using silk produced by glands in the caterpillar’s mouth. Moth caterpillars create cocoons as protection during the process of transformation (metamorphosis).
Chrysalis: A firm casing created during the final molt before a caterpillar undergoes metamorphosis. The casing is an adaptation of the exoskeleton. Most butterflies form chrysalises rather than cocoons.
Adult butterflies feed on many items including rotting fruit, animal waste and, most commonly, the nectar found in many flowers.
Pesticides negatively impact the butterflies’ native plant communities and their use should be reduced or eliminated. Creating gardens can restore the lost habitat of local butterfly species.
A host plant is a plant that a female butterfly selects to lay her eggs on. She chooses the plant carefully because the larvae will feed on the plant once they hatch.
