native to Australia, introduced to the US (FL 1997)(1)
in FL established in dry or seasonally wet habitats but failed to establish in fully aquatic habitats due to a lack of suitable pupation sites(1)
Host: broad-leaved paperbark (Melaleuca quinquenervia
. It also feeds on other members of the Myrtaceae family, including native ones, but doesn't seem to cause serious damage.
Female lays about 470 eggs in her lifetime. Larval development takes about 28 days. Drop to the ground to pupate. Total time from egg to adult about 48 days.
introduced to control its host, Melaleuca quinquenervia
, an invasive weedy tree from Australia(1)
