Malayan Jungle Nymph

Heteropteryx dilatataตั๊กแตนกิ่งไม้

Part of this is not on the page we cite. We opened it on 10 Aug 2026 and some of the degrees above are not stated there. The values above may still be right, but we cannot show you where they came from, and nobody here has checked them against a second source. Anything about a sick animal goes to a qualified exotic vet, not to a page. keepinginsects.com

Drag the sun. Malayan Jungle Nymph is nocturnal, so what it is doing changes with the light.

Adult size

14–17 cmNose to tail, adult

The size the sheet states for a grown animal.

Why

Two drawings, because they answer two questions. The silhouette is at true scale against a 1.75 m person: it says how big this animal actually is, which no number does for someone who has never seen one. The bar under it is logarithmic and shared by every sheet here, so a 2 cm isopod and a 4 m python both stay readable on the same axis and two species can be compared at a glance.

Drawn from the stated numbers. Only what the sheet states is drawn inside.

Why

The rectangle carries the exact width-to-height ratio of the figures above it, and the ruler under it places that width on the 0–250 cm scale every sheet here shares, so two species still compare at a glance. Nothing is added that the sheet does not name: a lamp drawn on a sheet that never mentions one would be invented equipment. What the sheet leaves out is listed rather than left blank, because an empty tank reads as « none needed ».

What your climate adds

This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.

Diet

Feeding rhythm

Food stays available

The sheet states food is always present rather than given on a cycle, so there is no interval to draw.

The sheet statesBramble (staple), oak, rose, raspberry, eucalyptus, guava · Fresh leaves always available; replace ~weekly

Staple food

Behaviour and handling

HandlingF risky: powerful spiny-leg pinch; handle low & slow, support body
CommunalYes: tolerant in groups with space
Defense / stress signsRears, spreads and snaps spiny hind legs; stridulates/hisses

Reproduction

Life course

Day 0Hatch
1–1.5 yrLifespan in care
1 yrMinimum commitment
Sexual maturityNot in our data

Read from the lifespan and maturity the sheet states, for animals in care and not in the wild.

Why

The minimum commitment is the low end of that lifespan, and the reproductive window is what is left after maturity: both are subtractions on stated figures, not figures of their own. The sheet also reports a record of about 0.2 years; that is a reported maximum, not the range to plan for.

Reproduction
F buries seed-like eggs with ovipositor; hatch after 7–14 mo; sexual

Common health problems

Common health issues
SignsMismoult if floor too dry/low, dehydration, prolapse in F

SignsSluggish, shrivelled, mould, failed egg-laying

Good to know

  • The bright-green female is one of the heaviest insects on Earth

What it needs

Enclosure at least 40 × 40 × 50 cmbecause enclosure — 40×40×50 cm (H ≥3× body); mesh for moulting
A thermometerbecause temp — 20-30°C
A hygrometerbecause humidity — 70–90%

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation.

Every field this product runs on is stated here. That is not a claim that the values are right: it says what the sheet states, not whether it is true. Whether a human has read it is the badge at the top of this page.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
