Dwarf Spiny Stick Insect

Dares ululaตั๊กแตนกิ่งไม้

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. amentsoc.org

Drag the sun. Dwarf Spiny Stick Insect is nocturnal, so what it is doing changes with the light.

One ambient band, 22–27°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.

Identity

4 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, raspberry (Rubus spp.) · Fresh leaves always available; replace ~weekly

Staple food
Bramble (staple), oak, raspberry (Rubus spp.)

Behaviour and handling

HandlingDocile; tiny: observe rather than handle
CommunalYes: gregarious with hides
Defense / stress signsPlays dead; tucks legs; freezes in litter

Reproduction

Life course

Day 0Hatch
0.7–1 yrLifespan in care
0.7 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
Sexual; eggs buried; hatch ~4–6 mo

Common health problems

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.
