About the Formosan Giant Mantis

Titanodula formosana, also known as the Formosan giant mantis, is a species of praying mantis in the subfamily Hierodulinae. T. formosana is found in China, Taiwan, Malaysia and the Sunda islands. T. formosana was originally placed in Hierodula, but a 2020 study moved the species to a new genus, Titanodula, based on its large size and the unique shape of the male genitalia. Wikipedia →
