Intermediate forms

Intermediate forms of the gaudy commodore are rarely captured, but do occur. These display a wide range of mixtures of the wing patterns of both forms and most likely occur during times of unstable thermal shock or stress. 

In both forms males and females are alike. 

This variation is also expressed in the spiny final-instar larvae of this species, which are black when reared at the lower temperatures associated with the winter form and bright orange when reared at the slightly higher summer temperatures.
