Desert hairy scorpion

Hadrurus arizonensis

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. thetarantulacollective.com

Drag the sun. Desert hairy scorpion 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.

The numbers

Temperature

152025303540 °C
28–35°Ambient

One ambient band, 28–35°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.

The sheet states28-35°C (hot end), cooler night

Humidity

30–50%Target RH

The sheet states30-50% (dry); slight moisture at burrow base

Identity

Adult size

1.75 m11–14 cm
1520100400 cm
11–14 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

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, locusts · 1 item weekly to biweekly (eats sparingly)

Staple food
Crickets, roaches, locusts
Feeding frequency
1 item weekly to biweekly (eats sparingly)
Supplements
Not required

Behaviour and handling

HandlingDiscouraged: not medically dangerous but defensive; a painful sting/pinch
CommunalNo: solitary and cannibalistic; house alone
Defense / stress signsTail raised, pincers open, deep burrowing

Reproduction

Life course

Day 0Hatch
15–20 yrLifespan in care
15 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
Viviparous; young ride mother's back to first molt

Common health problems

Common health issues
SignsFatal if kept humid (mycosis/mould); mismolt; sensitive to dampness
Red flags / quarantine
SignsReject damp/mouldy specimens; keep bone-dry; QT wild-caught (most are WC)

Good to know

  • Can live ~20 years and glows vivid green under UV

What it needs

Enclosure at least 40 × 30 × 30 cmbecause enclosure — 40x30x30 cm for one adult (deep substrate)
A thermometerbecause temp — 28-35°C (hot end), cooler night
A hygrometerbecause humidity — 30-50% (dry); slight moisture at burrow base

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation.

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.
