The Pseudocreobotra wahlbergii is variable in colour, being typically light green, but it can equally be tinted yellow, pink or red. It has a large eyespot on its forewings, which is typically black, green and cream and is surrounded by a green patch. The inner hind wings are orange and the outer hind wings are transparent. Nymphs are black until the third instar. While at rest, the Pseudocreobotra wahlbergii is a sufficiently good aggressive mimic of a flower that preys on insects (mostly flies and spiders) that attempt to pollinate it, at which moment the mantis seizes and eats them.
