Giant Leaf Insect

Pulchriphyllium giganteumตั๊กแตนใบไม้

Traceable. The figures above appear in the page we cite, which we opened on 10 Aug 2026. That means you can check them, not that we have confirmed they are right. keepinginsects.com

Drag the sun. Giant Leaf Insect is nocturnal, so what it is doing changes with the light.

The way of life is written in this sheet, word for word. The climate words summarise the two figures above them, they do not add to them.

One ambient band, 25–30°C. This sheet states no warm side, no cool side and no night figure, so none are shown. Same scale on every sheet here, so two species compare by eye.

Adult size

1520100400 cm
10–11 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 ».

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, guava, rose; older darker leaves · Fresh leaves always available; replace ~weekly

Staple food
Bramble (staple), oak, guava, rose; older darker leaves

Supplements

Behaviour and handling

HandlingVery delicate; minimise; support body
CommunalYes: gregarious
Defense / stress signsRocks like a leaf; freezes; may drop legs

Reproduction

Life course

Day 0Hatch
0.4–0.6 yrLifespan in care
0.4 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.

Reproduction
Eggs dropped; largely PARTHENOGENETIC (males very rare); hatch ~4–6 mo

Common health problems

Common health issues
SignsMismoult (needs RH + airflow), dehydration, leg loss
Red flags / quarantine
SignsBrowning, shrivel, mould, failed moult

Good to know

  • Often formerly listed as Phyllium giganteum; the biggest of the leaf insects

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.
