Life history
Males reach about half the size of females. The male larvae start early spinning a white cocoon. The pupa is made within and is black. The female pupa is yellow with grey stripes at the front and bright brown at the end. Males emerge in about two weeks, at the same time as the females who only need five days to develop.
