Habitat expansion of an exotic lace bug Corythucha marmorata (Uhler) was observed on the Kii Peninsula in 2003–2004, and on Shikoku Island between 2004 and 2007. The bug was first sighted in Nishinomiya City in Hyogo Prefecture in 2000, and then further south in central Kii Peninsula in 2003 before reaching the southern tip of the peninsula by 2004. The bug was first observed in the Tokushima and Ehime Prefectures of Shikoku Island in 2004, after which the range expanded and extended across the entire island by 2007. In this study, six wild Asteraceae species were identified as the host plants to the lace bug.
