Jungle Nymph key facts

Care level

Intermediate

Lifespan

Adult females 1-2 years / adult males 3-4 months

Size

Females 14-17cm and 30-65g, males 9-13cm

Diet

The leaves of broadleaf trees

Temperature & Humidity

It comes from tropical forest in the Malay Archipelago, so mist the enclosure against drying. Females are 14-17cm and heavy, so moulting needs real height and footholds strong enough to bear the weight.

Breeding & Egg-laying

The female lays into the ground using the secondary ovipositor at the end of the abdomen. Phasmid eggs resemble plant seeds, and in captivity they wait to hatch within the substrate.

Cohabitation

It is placid, and several of the same species can share an enclosure. Being touched during a moult easily spoils it, so give the container height and plenty of footholds. When alarmed it snaps the hind legs shut like scissors and defends itself with the spines on the tibiae, so handle it with care.

Lifespan & Rearing Period

Across stick insects as a whole, lifespans run from a few months to at most three years. Being a large species, it also takes longer to reach maturity.

Health & Notes

The import of insects, foreign stick insects included, is regulated under Japan's Plant Protection Act, and whether a given species may enter depends on the country it comes from. What circulates in Japan is captive-bred stock, so buy from a clear source and never let one loose outdoors. The eggs look like plant seeds, so always check the substrate for them before discarding it.

7 things to know before welcoming a Jungle Nymph

1. 1The Female's Impressive Size

   Females reach 14–17 cm in length and 30–65 g in weight, making them among the heaviest living insects, while males are noticeably smaller and slimmer at 9–13 cm. It helps to know this difference in advance so the adult size and appearance don't come as a surprise.

2. 2A Tall, Roomy Enclosure

   Because this species grows so large, the enclosure needs enough height for the insect to molt without getting caught. A cramped cage becomes more stressful as the animal grows, so it's worth choosing a size with its adult dimensions in mind from the start.

3. 3Calm Nature, Handle with Care

   Movements are slow and the temperament is generally calm. That said, the body is lined with spines, so gripping it tightly or forcing it to move can trigger a defensive reaction meant to protect itself.

4. 4A Diet of Fresh Leaves

   This is a herbivorous insect that feeds on plant leaves. Before bringing one home, make sure you have a reliable, ongoing source of fresh leaves ready.

5. 5Molting Is a Fragile Time

   Just before and after molting, the body is extremely delicate and sensitive to disturbance or dry conditions in the enclosure. It's best to leave the insect undisturbed during this period and avoid sudden changes to its environment.

6. 6Nocturnal and Quiet by Day

   This species is nocturnal and tends to stay still during the day. Little activity in daylight hours isn't necessarily a sign of poor health, so it helps to understand its natural rhythm before assuming something is wrong.

7. 7Wings That Can't Fly

   Although it has short wings, it cannot use them to fly. That means there's little risk of it escaping by air, but it can still walk away, so make sure the enclosure's lid and latches are secure.
