This Caterpillar was introduced deliberately into Australia in the Northern Territory to control an outbreak of:
The caterpillars bore into young shoots. This damages leaf and seed production by the weed, but does not completely eradicate it. More than 10 other species of insect have also been introduced in an attempt to control the weed.
The caterpillars also attack other plants from the Mimosa family ( MIMOSACEAE ), including :
Unfortunately, this last one is an important crop in some Asian countries.
The adult moth has dark brown forewings, each with a white stripe along the hind margin, a pale yellow diagonal line, and a broad white arc from wingtip to tornus. The hindwings are pale brown.
