Fun facts

  • Phylogenetic studies group it with the orchid mantis in a clade of flower mantises in which "the female is much bigger than the male" (Hymenopus, Helvia, Theopropus).
  • There's a record that, even when they hatch from the same egg case and grow under the same conditions, individuals can differ in color among reds, greens, and yellows (the data is limited, so it isn't certain).
