They are found in Malaysia, Hawaii, India, Nepal,[2] Italy (San Paolo Solbrito), Indonesia (Java, West Sumba,[3]), Korean Peninsula, Philippines, New Guinea, southern China, Taiwan, Vietnam, and Japan (Honshu, Shikoku, Kyushu, Okinawa).

Its distinct appearance make this species recognizable due to elongated prothorax and slender body, in which contributes into its overall stick structure.

This species can be seen around the South East Asia region, it inhabits grasslands and forest in where it appearance can be effective due to its ability to camouflage.

This type of behaviour is combined with the arching of the abdomen, exposing its dorsal surface and pumping movement in which releases chemical signals such as pheromones which primarily attracts males.

[11] The responsive predatory behaviour observed in mantises such as the stalking behaviour is based on temperature, showing direct relationship with to changing climate conditions[10] In the world of prey-predator relationship, the praying mantis, H. patellifera, exhibits a unique behavioral adaptations due to environmental pressures.

[12] Furthermore, the color polymorphism observed in H. patellifera, from vivid green to muted brown provides a significant advantage for mantises to blend seamlessly with their environment.

In a field experiment, mantid was observed exhibiting a "peering" movements swaying back and forth while advancing toward its prey (moth).

[10] In a field study conducted in the Quetta and Pishin districts in Pakistan, over 380 specimens on H. patellifera were collected; this marks the first record of this species in the Pakistani region.

[15] Pigment within the compound system aligns with light-dark cycles, it has been observed that it darkened during night and lightens in the morning.
