We investigated aquatic insects in fallow fields on Amami-Oshima Island in March 2020. We found nine species including eight Coleoptera and one Heterop- tera. The large-bodied aquatic coleopteran beetles Cy- bister tripunctatus lateralis and C. surgillatus were found, but C. rugosus and Hydrophilus acuminatus were not found in our survey.
