Entomoscelis americana
red turnip beetle
Entomoscelis americana is a leaf beetle in the family Chrysomelidae, commonly known as the red turnip beetle. It is native to North America, primarily distributed between 45° and 68° north latitude within the Western Cordillera and Interior Plains physiographic regions. The species is associated with forest, forest-grassland, and grassland vegetation types. In 2020, it was synonymized with the Palearctic species Entomoscelis adonidis, though this relationship was historically disputed based on morphological differences in male genitalia.
