Hoshihananomia octopunctata

Distinguished from other tumbling flower beetles by the eight-spotted pattern on the elytra, referenced in both the scientific epithet "octopunctata" (eight-spotted) and the common name. Members of the genus Hoshihananomia can be separated from related genera by genitalic and antennal characteristics, though specific diagnostic features for H. octopunctata require specialist examination.

North America, with confirmed records from Ontario and Québec in Canada, and Vermont in the United States.

Exhibits tumbling behavior typical of Mordellidae: when disturbed, the beetle flexes its body and uses its large hind legs to launch itself into a tumbling flight, making capture difficult.

• Other Hoshihananomia speciesCongeneric species share the general body form of Mordellidae and require detailed examination of genitalia, punctation patterns, and antennal structure for reliable separation.
• Other Mordellidae generaAll tumbling flower beetles share the characteristic hump-backed body shape, pointed abdomen, and tumbling escape behavior; genus-level identification requires examination of antennal club structure and body proportions.
