Young shoots are densely hairy and therefore silvery in appearance, with hairs 0.25-2 mm long, which are appressed on the leaves and ascending on the twigs (Blake, 1968). Surveys in Australia for potential biological control agents of M. quinquenervia for possible release in Florida, USA have revealed several promising insect species (Center, 1992; Balciunas and Burrows, 1993; Balciunas et al., 1993a, b; Purcell and Balciunas, 1994) and several biological control agents have subsequently been released.
