to Kisenbaru, including Kanna Dam. Though the best wetland is located
within the U.S. Army base, wetland environment is also found in
surrounding areas outside the base. It is one of the few places
in Okinawa where occurrence of Lethocerus deyrollei and Diplonychus
rusticus was recorded in the past. Even now, there are many
aquatic hemipterans such as Ranatra unicolor (a rare species
listed in the RDB of Okinawa Prefecture), and Saldoida armata. |
