These Caterpillars feed on the introduced weed:

  • Groundsel Bush ( Baccharis halimifolia, ASTERACEAE ).

    The adult moth has brown patterned forewings and faintly patterned brown hindwings. The wingspan is about 0.5 cm. The species has several generations each year.

    The species is found naturally in

  • Florida, USA.

    The species was introduced into Australia deliberately from USA to control its foodplant which was invading pastures. The caterpillars were tested on 65 different plants. They walked away from the 64 other plants, and only fed on the Baccharis halimifolia. Attempts at mass rearing began in 1969, but failed. Rearing was begun again in 1984, and it was 1986 before sufficient numbers were obtained for release. It was released in 1986 and 1987 in

  • Queensland.

    However later surveys showed that the species probably did not establish in Australia.
