Tolidomordella discoidea

As a member of Mordellidae, this species likely exhibits the family's characteristic wedge-shaped body form, with the abdomen tapering to a point and the hind legs enlarged for the jumping, tumbling escape response that gives these beetles their common name. The subspecies flaviventris, described by Smith in 1883, presumably differs in abdominal coloration (yellowish venter) from the nominate form. Specific diagnostic features distinguishing T. discoidea from congeners are not documented in available sources.

North America. Specific range details beyond continental occurrence are not established in available literature.

Has been observed exhibiting the tumbling escape response characteristic of Mordellidae, where beetles use their enlarged hind legs to launch themselves into the air, tumbling erratically to evade predators.

• Other Tolidomordella speciesCongeners share the wedge-shaped body, tumbling behavior, and general habitat preferences; specific distinguishing characters require examination of subtle morphological details not summarized in available literature.
• Other Mordellidae generaFamily-level characters including body shape and escape behavior are shared across Mordellidae; genus-level distinctions rely on antennal structure, body proportions, and genitalic features.
