Hierodula membranacea

About Hierodula membranacea

Hierodula membranacea is a large, robust mantis from tropical and subtropical Asia. It is one of the most widely kept praying mantids in the hobby, and for good reason — it is hardy, tolerant of a range of conditions, and has a strong feeding response that makes it straightforward to care for.

Adults are typically bright green, though brown individuals appear occasionally. Like all mantids, H. membranacea undergoes incomplete metamorphosis: eggs hatch into tiny nymphs that resemble miniature adults, moulting repeatedly as they grow. There is no larval or pupal stage.

Total lifespan is around 12 months from hatching. Males are slimmer and shorter-lived than females, and mature 1–2 moults earlier.

Enclosure

Height is critical. Mantids hang upside-down to moult, and a failed moult is usually fatal. The enclosure must be at least three times the mantis's body length in height. For an adult H. membranacea, that means a minimum of 27 cm tall — taller is better.

The ceiling must be mesh or textured material. Smooth plastic or glass ceilings prevent the mantis from gripping, causing it to fall during moulting. This is the single most common cause of death in captive mantids.

• Net cages, mesh-topped terrariums, or converted tall containers all work well
• Add twigs and branches for climbing and perching
• Good ventilation is essential — stagnant air encourages mould
• House individually. Mantids are solitary predators and will cannibalise cage-mates regardless of hunger

Temperature, humidity & misting

This species tolerates a broad range. Keep at 22–28°C during the day with a slight night drop. Room temperature in most UK homes is fine in summer; a small heat mat on the side of the enclosure helps in winter.

Mist lightly every 1–2 days. The mantis will drink droplets from the mesh or walls. Aim for 50–70% humidity — this species is forgiving, but avoid both bone-dry and waterlogged conditions.

Feeding

H. membranacea is a voracious feeder that rarely refuses prey. Offer live prey only — mantids will not eat dead or pre-killed food. A good size guide: prey should be roughly the length of the mantis's raptorial forelegs or smaller.

• Small nymphs: fruit flies (Drosophila)
• Medium nymphs: small crickets, greenbottle flies
• Sub-adults and adults: locusts, large crickets, moths, bluebottle flies

Feed every 2–3 days. Do not overfeed — a visibly distended abdomen increases the risk of moulting failure. If the abdomen looks swollen, skip a feed or two.

Moulting

Pre-moult signs include refusing food, becoming sluggish, and hanging upside-down for extended periods. Do not disturb a moulting mantis. Do not mist directly during a moult. Ensure the enclosure has adequate height and a textured ceiling well before this point.

After a moult, the mantis will be soft and pale. Wait at least 24–48 hours before offering food again to allow the exoskeleton to harden.
