Distribution and habitat

The diurnal Indonesian Double Shield Mantis originates from Indonesia from the island of Flores. There they inhabit shrubs and trees of the tropical forests.

Maintenance

A terrarium or insectarium of the size 40 x 40 x 40 cm (L x W x H) can be recommended as a guideline. The most suitable container is one with a cover made of gauze or a fine metal grid, which should be placed in a quiet place without sunlight.

You will need an insectarium not too densely structured with finger-thick climbing branches (hiding places, privacy screens), climbing plants and pieces of bark, with a cork back wall, as well as a small, shallow drinking vessel with water gel or a cotton trough. Artificial or live plants (e.g. Ficus pumila, Scindapsus aureus) can be used for decoration. The substrate of coconut fiber, vermiculite or sand-loam-peat mixture should always be kept slightly moist. Daily, the insectarium should be finely sprayed with water inside (humidity), but a rain or mist system is better. Waterlogging should be avoided at all costs.

Temp. day: 24-30 °C

Temp. night: 18-22 °C

Humidity: 60-80

The lighting duration should be max. 12 hrs. Light sources that also produce the necessary heat are ideal.

Diet

They are predatory and seize even very large prey, preferably flying insects, at lightning speed with their spiny tentacles. The food supply consists of fruit flies (Drosophila), flies, house crickets, crickets, grasshoppers, cockroaches, small arachnids, etc., according to their size. It is important to regularly add minerals and vitamins (e.g. by dusting the feeders). The quality of the feeders can be enhanced by feeding overripe fruit and honey water. A few days before, during and after molting, they refuse to eat. No predatory feeders (e.g. crickets) should be left in the insectarium during molting, as during this time the animals are unprotected and may become prey themselves. Food should only be offered every 2-3 days. A varied diet promotes health and prevents deficiency symptoms.

Reproduction and breeding

Adult females are slightly larger and stronger than the slimmer males. Males have 8, females only 6 abdominal segments. Females are sexually mature 4-8 weeks after the last molt (imaginal molt), males already after about 2 weeks

After mating, which lasts several hours, the female lays the first of several egg packages (oothecae) after 2-4 weeks. At a temperature of 28-30 °C and a humidity of about 60%, up to 100 or more larvae hatch after 6-8 weeks. They should be fed immediately with small fruit flies or micro echinoderms so that they do not eat each other (cannibalism).

After imaginal molting, females live about 18 months, males about 12 months.

Important

They are very aggressive and keeping them in groups is only possible until L2/L3. At the latest after L3 they must be separated

Before mating, the female should be offered a large food animal to reduce the risk of her eating the male

They have very good camouflage due to their body shape and coloration as well as their often long-lasting motionlessness and are very similar to a leaf (leaf mimesis).

For molting, they hang upside down in the branches or on the lattice cover and slide out of their old cover. Therefore they need at least one body length of free space below them.

Before purchasing, an insectarium should be prepared that meets the species-specific needs. Good ventilation without drafts is necessary, as well as equipment for measuring temperature and humidity. The lighting must correspond to the day-night rhythm appropriate for the species and must be installed in such a way that the animals cannot injure themselves. The insectarium should be locked in such a way that neither unauthorized persons can open it nor the animals can escape. Special attention must be paid to thorough hygiene and contamination must be removed regularly.
