Animal Facts
The cloudless sulphur is a migratory butterfly, with populations from the USA often travelling to Mexico or the Caribbean to overwinter.
When migrating, the cloudless sulphur can travel 20km a day.
The cloudless sulphur is often observed feeding from mud; it is thought that this may be a source of salt for the butterfly.
The chrysalis of the cloudless sulphur looks like a leaf, and the pupa inside will wriggle when touched to scare off predators.
The egg of the cloudless sulphur is pure white when first laid, but becomes yellow-orange as it approaches hatching time.
