Hadrurus spadix
A large scorpion of around 15cm from the deserts of southern North America. Its uniformly black carapace separates it from the related giant desert hairy scorpion. It spends much of its time digging and enlarging its burrow.
Hadrurus spadix is a large scorpion, around 15 cm long, native to the southern deserts of North America. Commonly called the black-back scorpion, it is told from the similar giant desert hairy scorpion by its completely black prosoma. It is strongly fossorial and spends much of its time digging and enlarging a burrow. Substrate should be mostly sand with some peat, moistened so that it packs and then dried before the scorpion is introduced, so that burrows hold their shape. A rock or piece of bark gives it something to dig beneath. The species wants heat, doing best at 30-35 C by day with a sharp drop to about 20 C at night to mimic desert conditions. It is nervous and can behave aggressively; the venom is considered low in toxicity but the sting is quite painful. Prey is located by vibration, so sluggish food items are harder for it to find.

The Black-back Desert Hairy Scorpion lives 10-18 years.
The Black-back Desert Hairy Scorpion grows to About 15cm total length.
No water dish is needed, and humidity is kept low, around 30%, to prevent mycosis.

It wants heat: 30-35 C by day with a drop to about 20 C at night to mimic desert conditions. Keep humidity low, around 30%, to prevent mycosis.
Use deep substrate of mostly sand mixed with peat; moisten it so it packs, then dry it so burrows hold. A rock or piece of bark gives it something to dig under. A water dish is said to be unnecessary.
Feed small insects, crickets being the usual choice. It locates prey by vibration, so inactive food is harder for it to find.
Nervous, and it can display aggressively. The venom is usually considered low in toxicity, but the sting can be quite painful.
Substrate that stays damp invites mycosis. The scorpion often pauses before feeding, for reasons that are not understood.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Black-back Desert Hairy Scorpion is 10-18 years. With proper care and nutrition, they can live a long and healthy life.
Black-back Desert Hairy Scorpion typically reaches About 15cm total length as an adult. Size may vary depending on care conditions and individual genetics.
Black-back Desert Hairy Scorpion feeds on: Small live insects, most commonly crickets. Aim for a balanced diet with appropriate feeding frequency.
