Odontomantis planiceps is completely black from the 1st to 3rd instar, with green bands at the edges of every thorax segment.

[2] Odontomantis planiceps is a very common mantis throughout its range, readily acclimating and even thriving in urban gardens and inhabiting ornamental plants.

The geographic distribution of this mantis is wide, with most specimens collected in the Southeast Asian range from Malaysia to Indonesia, and this species has even been reported in Hong Kong and Taiwan.

[3] Odontomantis planiceps usually stands still on leaves waiting for prey to pass.

If there is an assumed threat, it will quickly retreat to the bottom of its leaf, while adult males will not hesitate to fly.
