About Notched Pygmy Backswimmer
The only species of the pygmy backswimmer family found in Japan, with a small, hemispherical body about 2.5-3mm long. Like the water boatman-relative backswimmers, it swims upside down. Known only from Amami Oshima and Tokunoshima, it is endemic to the Amami Islands, and lives in slow-flowing rivers, in spots where plant roots hang down from the bank into the water. It is listed as Vulnerable (VU) on the Ministry of the Environment's insect Red List.
