Giant Australian Mantis (Hierodula majuscula)

Hierodula majuscula

The Hierodula majuscula, or Giant Australian Rainforest Mantis. It is the undisputed titan of Oceania and the largest Australian mantis, as well as one of the most colorful. Upon reaching adulthood, it reveals its most spectacular trait: the inside of the raptorial legs is tinged with intense Cherry Red, Cobalt Blue and Black, revealed in a magnificent threat posture (deimatic display). Slightly more demanding than its Asian cousin (H. membranacea) in terms of heat and very high humidity, it compensates with legendary voracity and an immense size (up to 4.3 inches). Identical management: tall terrarium, mesh for grips and abundant diet based on mobile insects. Exhibits ruthless cannibalism.

Species description

Geographic Origin and Habitat: The study places Hierodula majuscula in the wet tropics region of eastern Australia.
Taxonomy and Genetics: The article is a species-specific behavioural study; it does not present a taxonomic revision or genetic diagnosis.
Behaviour and Habits: Experimental animals displayed more often to tactile than non-tactile simulated predator stimuli in that study; this is an experimental result, not a complete behavioural profile.
Morphology and Sexual Dimorphism: The source describes bright green dorsal colouration and red/purple patches on the ventral pronotum and inner forelimbs. It reports adult females around 10 cm, with males slightly smaller and more mobile; those observations are study context, not an identification key.

Care, breeding and tankmates

Terrarium Setup: In one behavioural experiment, individuals were housed separately in inverted transparent cups with mesh for airflow. This was an experimental protocol, not a general enclosure standard.
Lighting and Heating: The experiment used 25–26 °C and a 14 h light:10 h dark cycle; these values are reported study conditions, not a universal care recommendation.
Humidity and Hydration: The experiment used 55–60% humidity and daily watering; it did not validate a species-wide husbandry range.
Feeding and Supplementation: Experimental animals received crickets three times weekly until maturity; no supplementation regime was tested.
Compatibility and Cohabitation: The study housed mantises individually and did not test cohabitation.
Health and Common Diseases: The source is a behavioural experiment, not a clinical study.

Adult size
10 cm
The catalog's scalar value is 10 cm. The O'Hanlon et al. — Hierodula majuscula source reports a maximum adult measurement of 10 cm for this species, recorded as total length (TL). The taxonomic record consulted is Hierodula majuscula. These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
