Early instars of these Caterpillars of this species are dark blue with one or two orange diagonal stripes, and have short spines along the body, and longer ones on the thorax and ninth abdominal segment. In later instars, the orange stripes become green and the spines degenerate to coloured knobs. The last instar is mainly green, with some dark markings on the sides.

    Usually seen rapidly flying in one direction at a constant height, they only occasionally land, and catching one is a real thrill.

    The eggs are pale yellow and spherical. They are usuallly laid singly on the upper surfaces of leaves of a foodplant.
