Orchithemis pulcherrima - Colour Forms

Among the many libellulid species in Peninsular Malaysia, Orchithemis pulcherrima may be one of those with the most number of colour forms. These colour forms are not due to level of maturity. Two colour forms (red and dark blue) exist in male while three (red, dark blue and yellow brown) are for female. For male, the red form is the more common one. On the other hand, yellow brown is more common for female. The red form female is said to be rare. I have seen all these colour forms of male and female except the red form female.
