Coconut rhinoceros beetle (PEST)

Oryctes rhinocerosด้วงแรด (also ด้วงมะพร้าว)

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

Drag the sun. Coconut rhinoceros beetle (PEST) is nocturnal, so what it is doing changes with the light.

National law is not global, and we hold no national wildlife law for any country, Thailand included. Check your own authority before buying or selling.

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.

Reproduction

Life course

Day 0Hatch
0.3–0.8 yrLifespan in care
0.3 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 in rotting palm/compost -> L1-L3 -> pupa -> adult

Good to know

  • Included as an honest warning: a major palm pest whose fat grubs are a popular fried snack in Thailand

What it needs

A thermometerbecause temp — 26-32C
A hygrometerbecause humidity — 60-85%
Not stated: The size of the enclosurethis sheet describes the enclosure without a figure: « Not advised to culture (palm pest); if reared for food, deep compost bin, contai »

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 6 of 7 of the fields this product runs on. What is missing turns something off: enclosure size audit. 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.
