Asian trapdoor spider (Cyclocosmia)

Cyclocosmia spp. (e.g. C. ricketti, C. latusicosta)

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. en.wikipedia.org

The numbers

Temperature

22–27°Ambient

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.

Enclosure
Tall enclosure, 12-20 cm deep substrate for one spider

Identity

3 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.

Diet

Feeding rhythm

every 7 dAs the sheet states
4Meals in 28 days

Twenty-eight days, one row. Each band is a meal window.

Why

The windows widen as they go because the interval is a range: four meals after a 10–14 day cycle land anywhere between day 40 and day 56.

The sheet statesCrickets, roaches offered near the burrow · 1 item weekly to biweekly

Good to know

  • Its abdomen ends in a hard ribbed disc it uses like a manhole cover to seal its burrow: earning the name 'tornado/manhole spider'

What it needs

A thermometerbecause temp — 22-27°C
A hygrometerbecause humidity — 70-85%
Not stated: The size of the enclosurethis sheet describes the enclosure without a figure: « Tall enclosure, 12-20 cm deep substrate for one spider »

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

This sheet states 5 of 7 of the fields this product runs on. What is missing turns something off: enclosure size audit, day/night engine and awake count on the globe. We show the gap rather than fill it with a plausible number.

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.
