What is the difference between a male burmy and a female burmy?

A male Burmy evolves into a Mothim and a female Burmy evolves into a Wormadam. Burmy will evolve at lv. 20.

By the way, the cloak and type of Wormadam all depend on where she evolved: Plant Cloaked Wormadam is be a Grass-Bug type. (Evolution in a forrest)

Sand Cloaked Wormadam is be a Ground-Bug type. (Evolution in a cave)

Trash Cloaked Wormadam is be a Steel-Bug type. (Evolution in a town or building) -------------------------
