Bicoloured arboreal ant ( maeng tanoi )

Tetraponera rufonigraมดตะนอย

The page we cite does not state this figure. We opened it on 10 Aug 2026 and it gives no temperature for this species at all. 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

Day

Drag the sun. Bicoloured arboreal ant ( maeng tanoi ) is diurnal, 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.

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.

Good to know

  • Locally called 'mot tanoi'; its sting is a well-documented cause of ant anaphylaxis in Thailand

What it needs

Not stated: The size of the enclosurethis sheet describes the enclosure without a figure: « Twig/tube founding; arboreal nest (hollow wood) + outworld »

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.

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.
