There also are variations in their biology and control, so the following extension material must be applied only as appropriate to the region.
The iridescent green colour of the undersides is a structural colour caused by diffraction and interference of light by microscopic repeating structures forming a diffraction grating in the wing scales. [4] The caterpillars are green with yellow markings along the back. [1] Like other members of the family they are rather sluglike.
