Rhombodera stalli “Malaysian Giant Shield Mantis”

Rhombodera stalii – Giant Shield Mantis with an Impressive Silhouette

A broad, leaf-like pronotum, powerful antennae, and an alert gaze. Rhombodera stalii has everything that makes a large praying mantis so fascinating. Amid green leaves, its body shape blends seamlessly into its surroundings. But as soon as a prey item approaches, it shows just how quickly it can react.

The laterally widened neck shield is particularly noticeable in females. It is located directly behind the head and gives the giant shield mantis its distinctive shape. The females also appear sturdier and broader than the slimmer males.

A terrarium with space for climbing and shedding

For an adult, a terrarium measuring approximately 20 × 20 × 30 cm (W × D × H) provides a good starting point. Larger females benefit from additional space. Above all, it is important that there is sufficient headroom beneath a secure perching spot. This is because during molting, the mantis hangs upside down and must be able to pull its body completely out of the old exoskeleton.

Therefore, set up the terrarium with branched twigs, textured climbing surfaces, and a few plants. The decor should not block the open space beneath the molting sites. A securely fastened piece of suitable mesh in the upper area provides additional grip points.

Keep your giant shield mantises separately. Even with plenty of food, they may prey on one another.

Heat, Humidity, and Fresh Air

As a general guideline based on keeper experience, a temperature of about 24–28 °C during the day is suitable. Check the temperature where your mantis is sitting. It can get significantly warmer under a lamp than in the lower part of the enclosure.

Moisten part of the substrate and, if necessary, lightly mist the leaves or the side walls. The droplets provide a source of water. At the same time, the terrarium needs good ventilation so that surfaces can dry out again.

What does Rhombodera stalii eat?

The giant shield mantis eats live insects of an appropriate size. For example, small nymphs are fed fruit flies. As they grow larger, they can be fed larger flies and, accordingly, small cockroaches.

Start by offering a suitable portion every one to three days. This general guideline for mantises should be adjusted based on the size of the mantis and its prey. If the abdomen is still noticeably full, wait before offering the next meal.

If the mantis refuses food and retreats to molt, remove any remaining prey. Leave it alone during the molting process. Afterward, its body and antennae must harden before it can catch prey again.

• Green coloration that provides good camouflage among plants
