This is a smaller species than Harmonia arcuata , and not so abundant in Guam. It was recorded under the name Coccinella repanda by Fullaway in 1911. It feeds on plant lice. We collected it in only a few places. This ladybeetle has a wide distribution from China, India, Singapore, Java to New Caledonia, Queensland, New South Wales, and Tasmania. It is not known when it first appeared in Guam. Our specimens were determined by P. H. Timberlake.
